Hillary Clinton holds her Metrocard as she goes through the turnstile to enter the subway in the Bronx on April 7. Clinton hopped on the 4 train at Yankee Stadium and rode it uptown to the 170th St. Station with Bronx Borough President Ruben Diaz Jr.
Though the former New York senator said she last rode the train only a year or two ago, she seemed to have some trouble with the turnstile. Clinton had to swipe her metro card four times before making it through.

Ted Cruz waves to a supporter as he arrives for a campaign stop at the Sabrosura restaurant in the Bronx on April 6.
Cruz is hoping to take advantage of the state's rules to pick up scattered delegates across the state and put behind his infamous criticism of Trump and his "New York values." The rule for obtaining delegates is that in any congressional district in which a candidate doesn't win 50 percent of the vote, the winner gets two delegates while the second-place finisher gets one.
