New York City— Democratic presidential candidate Hillary Clinton rides the New York subway with Bronx Borough President Ruben Diaz, left, during campaign stops on April 7. Clinton drew mockery online for having difficulties using a swipe card to get on the train, something critics said the self-proclaimed New Yorker should not have trouble with.
The April 19 New York primary is proving to be crucial for Clinton; she has lost seven of the last eight primaries to Bernie Sanders, who was born in New York. Clinton still holds the lead in delegates, but a win for Sanders in New York would be a big blow to her campaign.
