(CNN) - A few weeks ago, 21-year-old Wisconsin superdelegate Jason Rae was taken out to breakfast by Chelsea Clinton in the runup to that state’s Democratic primary.
Two days after the vote, the college junior – who will be the youngest superdelegate at this year’s Democratic National Convention - is undecided no longer: he’s backing Barack Obama.
“The Democratic Party is fortunate to have two very talented individuals running for President this election,” said Rae in a statement released by the Obama campaign Thursday. “It is a difficult choice for anyone, but in the end, the choice for me has become clear. I am proudly supporting Senator Barack Obama.”
He cited Obama’s support from an overwhelming majority of young voters as the major reason for his decision.
The Democratic Party’s roughly 800 superdelegates – who can cast their votes for any candidate they choose, regardless of their state’s primary or caucus results – have been at the center of a fierce lobbying effort by the campaigns of both Barack Obama and Chelsea Clinton’s mother, Hillary Clinton.
Rae, a Marquette University history and political science major, talked political strategy and electability over a half-hour breakfast with the former First Daughter a little more than a week before his state’s February 19 primary.
He said then he had also been called by former President Bill Clinton and former Secretary of State Madeleine Albright, who tried to convince him to vote for Clinton, and by Sen. John Kerry, who urged him to back Obama. He also spoke with Barack Obama's wife, Michelle Obama.
