Go Hillary

-- WASHINGTON (CNN) -- Almost as many of Hillary Clinton's West Virginia supporters would vote for John McCain as would for Barack Obama, exit polls show.

If Obama were the Democratic nominee, 36 percent of Clinton supporters would vote for him in the fall, the polls found. But 35 percent said they'd cast their vote for McCain instead.

A big win for Clinton in West Virginia could raise doubts about Obama's electability in the general election.
