Political allies of Vice President Joe Biden have concluded that he can win the 2016 Democratic presidential nomination—even if Hillary Clinton enters the contest—and are considering steps he could take to prepare for a potential candidacy (Wall Street Journal). While Mr. Biden has made no decision about his future, people familiar with his thinking say, he hasn't ruled out a bid for the White House. If he runs, that could set up a titanic battle between two of the party's most prominent figures. Allies say Vice President Biden, visiting the USS Freedom in Singapore last month, could win the 2016 nomination. One step under discussion by Biden backers is to form a political action committee he would use to funnel money to other Democratic candidates, which could build goodwill for a possible White House bid, people familiar with the talks said. Meanwhile, Mr. Biden is preparing to attend a Democratic event in Iowa, which traditionally holds the first nominating contest, and to raise money this week for the Democratic governor of New Hampshire, the state that holds the first primary. Many prominent Democrats believe that Mrs. Clinton would be so heavily favored in a presidential primary that Mr. Biden and other party hopefuls wouldn't even contest the nomination were she to run. A recent poll in New Hampshire showed Mrs. Clinton leading Mr. Biden and other possible Democratic candidates by upward of 50 points. "I don't see Biden and Hillary running against each other," said David Axelrod, a senior strategist in both of President Barack Obama's presidential campaigns and who worked for Mrs. Clinton's New York senatorial bid in 2000. "I would be shocked to see that materialize." But Biden loyalists aren't writing off the idea. They say he has ties to elected officials nationwide, can attract crowds and money, and is a visible part of an administration that is popular with Democratic voters. "He's the vice president of the United States of America! When you're the sitting vice president and you're running against anybody, you still have a chance," said one person close to Mr. Biden.
