OFF THE RACES: Moving on up
CNN moved its primetime debate up by an hour to shorten the window between the undercard debate and the big event.
Software pioneer John McAfee says he's running for president.
A crowd of GOP candidates will attend a Republican tailgate party before the University of Iowa/Iowa State game on Saturday.
In a letter obtained by NPR, the conservative Latino group the Libre Initiative – which is funded by the Koch brothers - criticized calls for mass deportation and ending birthright citizenship made by some of the GOP presidential candidates.
Candidates are weighing in on the migrant crisis in Europe.
BIDEN: POLITICO writes that his decision may come down to what his wife decides.
BUSH: In a Wall Street Journal op-ed, he laid out his tax plan, which includes the consolidation of tax brackets and the slashing of the corporate tax rate from 35 percent to 20 percent.
He met yesterday with Heritage Foundation economist Stephen Moore, publishing executive Steve Forbes and CNBC contributor Larry Kudlow, reports the Washington Post.
The Huffington Post notes: "Bush will present a tax plan on Wednesday that curbs a lucrative perk for hedge fund managers and private equity magnates -- a proposals that mirrors those of his top rivals in the 2016 presidential election."
On Stephen Colbert's first episode of "The Late Show" last night, Bush said that his brother "should have brought the hammer down on the Republicans when they were spending way too much."
CARSON: He took a swipe at Trump's immigration plan, saying "People who say that have no idea what that would entail in terms of our legal system, the costs - forget about it."
And he told The Hill he's not going to change his low-key style. "I’ve heard people say, ‘You have to have more fire.’ They want me to stomp and bang my fists, but that’s not who I am. I’m a calm and rational person. You have to be that way as a neurosurgeon."
CHRISTIE: The CEO of United Airlines is stepping down amid a federal investigation that involves former Christie ally David Sampson. "United began a direct flight between Newark, New Jersey, and Columbia, South Carolina, where Samson has a summer home, while he was chairman and ended it days after he resigned last year. United, the dominant airline at Newark Liberty International Airport, was negotiating with the Port Authority over projects at the airport at the same time."
CLINTON: She reversed course, telling ABC News Tuesday that she is "sorry" for her use of a private email server.
The Wall Street Journal: "Hillary Clinton, in her last months as secretary of state, helped open the door to a dramatic shift in U.S. policy toward Iran: an acceptance that Tehran would maintain at least some capacity to produce nuclear fuel, according to current and former U.S. officials."
She's set to announce her plan to counter Iran's influence in the Middle East.
POLITICO rounds up her five-point plan on Iran, which the Clinton campaign views as "a prime opportunity to remind voters of her foreign policy experience and willingness to go beyond the White House."
KASICH: John Kasich says that his rivals are "already spilling acid on me."
He expressed some skepticism about his colleagues who have said they would "rip up" the Iran deal on their first day in office.
RUBIO: He said the party is "blessed" by the large GOP field.
PERRY: NBC's Alex Jaffe confirms that he's shuttered his South Carolina headquarters.
SANDERS: He's staffing up in South Carolina.
TRUMP: Here's his thoughts on taking in Syrian refugees: "I hate the concept of it, but on a humanitarian basis, you have to."
WALKER: He's launching a new site to highlight what he would do on "Day One" of his presidency.
Meanwhile, National Review looks at what went wrong with his candidacy. "Above all, the past few months have amplified questions about whether Walker’s campaign and, more importantly, the candidate himself are built to thrive on a stage larger and less forgiving than Wisconsin. Political observers had long worried about whether he had the charisma to succeed in a presidential contest. Now, there are doubts about his substance."
