Virginia Gov. Mark Warner’s decision to withdraw from consideration for the 2008 Presidential nomination has produced speculation at high levels of the Democratic Party that former Vice President Al Gore may run again.
Warner was to challenge front-running Sen. Hillary Clinton from the right, while Gore is on her left. Nevertheless, Gore succeeds Warner as the most likely “non-Hillary” to battle her for the nomination.
A footnote: Warner’s withdrawal, after nearly two years of pursuing national support, puzzles Democrats. Only a month ago, he was asking prominent members of the party to back him. Even after getting out, he still told friends he believes he could have won the nomination.
