Despite being hopelessly behind in pledged delegates and with only three primaries to go, Hillary Clinton refuses to give up. In fact, she continues to insist that she is more electable than Barack Obama.

Clinton told voters in South Dakota yesterday that her wins in swing states and her strong vote margins among certain groups make her more likely to beat John McCain in the general election.

At the same time, her campaign sent uncommitted superdelegates a letter with polling data showing how she could compete better than Obama in the fall. They pointed to her wins in states like Ohio and West Virginia along with her strong showings among older women, Hispanics and rural voters.

While Clinton has toned down her attacks on Obama in recent weeks, she has implied that if he becomes the nominee, the Democrats could lose in November.
