On the campaign trail, Senator Hillary Clinton is promising to continue her White House bid despite growing calls for her to exit the race. Many political analysts say Tuesday’s primary results in North Carolina and Indiana make Senator Barack Obama the presumptive nominee. Obama leads by about 150 delegates with six contests to go. On Wednesday, Clinton disclosed she’s lent her campaign $6.4 million over the past month, on top of a prior loan of $5 million.

Sen. Hillary Clinton: “I’m trying to make sure that their investment is a good one and because we are being outspent. Everybody knows that. We, historically, in the last several months have been outspent two-to-one, three-to-one, four-to-one, even five-to-one, but we’ve remained competitive, and I have been willing to loan that money to my campaign so that, you know, we could be competitive. And I think it’s paid off.”

Meanwhile, a prominent supporter of Clinton, former Senator George McGovern, has announced he’s switching over to endorsing Obama.
