Young voters in Michigan face hours-long line, same day voter registration to blame

Videos and photos circulating online Tuesday night show long lines wrapping down hallways and staircases in various polling locations as young voters waited for hours to cast their ballots in Michigan cities like Kalamazoo, Ann Arbor and East Lansing.

Colin Sherrod, 21, a college student at Michigan State University, waited over more than two hours to cast his ballot for Bernie Sanders. He registered on Tuesday and believes that’s one of the reasons why the voting lines seem excessively long.

"I think the main issue was because so many people tried to register on the same day. I’ve heard that wait time grew to four hours after I left," he told NBC News.

Officials in Ann Arbor also blamed same-day registered for the long lines.

"Ann Arbor has no waiting for people who are registered. Same-day voter registration, and everyone who isn’t registered, have been coming to the Clerk's Office,” City Clerk Jacqueline Beaudry said. "We have registered to close 1,000 people. This is the first time we have implemented this."

Michigan State University College Democrats told NBC News that polling stations were ill-prepared to deal with the amount of students that turned up to vote and information about how to register wasn’t communicated well. 

"Student groups on campus are trying to keep voters in line by having food and drinks at the polls to keep people spirits up and make sure they vote," the group said in a statement. 

NBC News Exit Poll: Union voters in Michigan and Missouri favor Biden

Biden held a clear advantage among union voters in two key contests tonight. In Michigan, where 3 in 10 voters live in union households, he won 54 percent of voters while Sanders won 42 percent, according to the NBC News Exit Poll. In Missouri, where 1 in 4 primary voters were union affiliated, Biden held a 60 percent to 35 percent edge.

NBC News Exit Poll: Support from key groups fueled Biden’s Michigan victory

A repeat performance of Bernie Sanders' surprise 2016 victory in Michigan was not on the cards for 2020.

The NBC News Exit Poll shows that Joe Biden won the state tonight with two-thirds of the vote from black voters, voters 45 or older, moderates and conservatives, and voters who made up their minds this month. 

Biden was also the clear favorite of voters looking for someone who can unite the country (82 percent) and voters whose top priority is beating Trump (61 percent).

With 125 delegates up for grabs, Michigan offers the biggest pledged delegate prize of the six states holding Democratic contests on Tuesday night. 

With more than half of the vote counted, Biden led Sanders 53 percent to 41 percent. 

As of 9:05 p.m. ET, NBC News projected that Biden will be awarded 38 pledged delegates from the state and Sanders will be awarded 33.

The NBC News exit poll from Michigan shows that Biden won the state with two-thirds of black voters, two-thirds of voters age 45 or over, 63 percent of moderates and conservatives, and 63 percent of voters who made up their minds this month. 

Biden was also the clear favorite of voters looking for someone who can unite the country (82 percent) and voters whose top priority is beating Donald Trump (61 percent).


Massive swing in large Michigan county from 2016 to 2020 could spell bad news for Sanders

Michigan results are trickling in as the final polls closed, and results in one large county show a huge swing from 2016 to 2020.

In Kalamazoo County — home of Western Michigan University and one of the state's 10 largest counties — Sanders is currently up by less than a point over Biden.

In 2016, when Sanders narrowly won the state, the Vermont senator won that county by nearly 23 points.

As is, Biden holds a nearly 10 point lead in the state with 32 percent of precincts reporting.

NBC News Exit Poll: Broad support underpins Biden’s Missouri victory

NBC News projected that Biden is the Democratic primary winner in Missouri, a state where the prior two Democratic primaries were decided by the thinnest of margins.

The NBC News Exit Poll shows that Biden’s support was broad-based, with especially strong backing among black voters and voters 45 or older. Biden was also the clear favorite of voters looking for someone who can unite the country and voters whose top priority is beating Donald Trump.

The race was fairly tight among the one quarter of Missouri primary voters who made up their minds in the last few days.

Sanders actually eked out a 51 percent to 45 percent edge among these voters, but Biden received a much larger cushion among those who came to a decision earlier this month, basically after the South Carolina and Super Tuesday results came in. Biden won this group by a 70 percent to 26 percent margin.

Both Biden and Sanders, however, will reach the necessary threshold to be awarded pledged delegates, NBC News projects.

Biden will be awarded 22 pledged delegates and Sanders will be awarded 15, as of 8:20 p.m. ET, according to NBC News.

There are 68 pledged delegates at stake in Missouri.

NBC News Exit Poll: Biden continues to run up score in South with win in Mississippi

Joe Biden added another Southern state to his primary scorecard tonight, scoring a huge win in the Mississippi primary contest. NBC News projected that Biden was the winner in the state at poll close.

According to results from the NBC News Exit Poll, the former vice president enjoyed a solid backing from the state’s sizable African American electorate, as we all as a strong showing among ideological moderates and those who attend religious services weekly or more.

Biden was the clear favorite among most demographic groups, including whites (66 percent), voters with no college degree (78 percent) and liberal voters (66 percent). But even as Biden racked up support among a broad coalition of voters, Sanders outperformed his 2016 margins among some groups.

In 2016, Clinton bested Sanders among liberal voters, as well as those younger than 45, but Sanders fared better among these groups compared to his lackluster performance among older, more moderate-leaning groups. Today, Sanders improved his margins among both groups, seeing double-digit increases in support among voters who consider themselves liberal on political matters, as well as those younger than 45.

But these gains were offset by the fact that tonight’s Mississippi Democratic primary electorate skewed older and more moderate than it did in 2016.

Biden has been awarded 21 delegates of the state's 36 pledged delegates. He had been expected to prevail in Mississippi and add to his delegate lead due to strong support from African American voters.

The Democratic primary in Missouri is too early to call, but Biden leads, according to NBC News.

North Dakota’s Democratic caucuses are also too early to call. 

There are 68 delegates at stake in Missouri. Fourteen are up for grabs in North Dakota.

Polls in the three states were the first to close among the six states voting Tuesday. The other states voting are Michigan, Washington and Idaho.

NBC News Exit Poll: In Missouri, fewer under 45 and black voters compared to 2016

There have been some shifts in the demographic profile of Missouri's primary voters since that 2016, when a razor thin margin of just over 1,000 votes separated Hillary Clinton and Bernie Sanders in the state.

Compared to four years ago, today’s Missouri Democratic electorate has fewer voters younger than 45, fewer black voters, and fewer self-described liberals, according to the NBC News Exit Poll results. It also has slightly fewer first time primary voters than in 2016.

Amid coronavirus outbreak, Trump still doesn't have any rallies planned

Vice President Mike Pence was asked at the White House coronavirus briefing on Tuesday whether the campaign will continue to have rallies amid coronavirus concerns. He told reporters: "I think that'll be a decision that’s made literally on a day-to-day basis" and "I’m very confident that the campaign will take the very best information and make the very best decision going forward."

The situation is clearly very fluid, given that the Trump campaign said they "expected" to reveal on Tuesday where the next rally would be but that was before the Biden and Sanders campaigns canceled their respective events in Ohio tonight. Of course, the day is not over so this Trump campaign announcement could still come but wanted everyone to have the proper context going into any such development.

See below for more on the events the campaign has "postponed" in recent days citing "scheduling conflicts," despite a claim they are "proceeding normally" (a "Women for Trump" bus tour through MI, WI, PA this week and a rare FLOTUS fundraiser in Beverly Hills on March 18). No information yet on future dates for either of these.
