One of the first CNN contributors to announce his prediction on Twitter was Alex Castellanos. In his latest column, he explains why he's betting fellow Republican Mitt Romney will win.

Democratic strategist Paul Begala disagrees with Castellanos' prediction. Right after the first presidential debate in which some were underwhelmed by President Barack Obama's performance, Begala remarked, "There is no doubt Romney had a good night. But I strongly doubt whether it was good enough." Begala's tweet reflects his prediction of a narrow win for Obama.

Castellanos and Begala saw each other's predictions and plan to duel it out with a wager. Stay tuned to see who has to shave his moustache or grow one.

Hilary Rosen, a Democratic strategist, is positive about the outcome for her party.

Politics: Long lines, sporadic snags in U.S. election

    Ari Fleischer, former White House press secretary in the George W. Bush administration, suspects that the election won't end Tuesday night -- that seven states could be decided by one percentage point or less. And if Romney can take Pennsylvania and Ohio, it "would be icing on the cake."

    John Avlon, a contributor to "Erin Burnett OutFront," said Sunday that the stakes are especially high in this election. Regardless of who wins, he says, "We cannot continue to allow extreme partisan distortions to define our policy debates and paralyze our capacity for constructive self-government." Avlon said he thinks Democrats have an edge.

    Maria Cardona, former communications director for the Democratic National Committee, sees Obama getting the Latino vote.

    Conservative William Bennett, who believes that "Romney has proven himself the man to lead America's comeback," predicts that victory will also go to his candidate.

    David Gergen, who has been an adviser to four presidents, notes that polls indicate the president got an important bump off of Hurricane Sandy.

    LZ Granderson, a CNN regular, makes a case for why he's rooting for Obama, saying that while the incumbent is not perfect, his concern for those less fortunate makes him worthy of a second term.
