Hillary Clinton seems like the likeliest next President, because she has a better chance of being the Democratic nominee than any of the top-tier Republican candidates (Paul Ryan, Jeb Bush, Marco Rubio, Chris Christie) does of being their party's nominee. So even though the Republicans have a better chance of winning, she has a better chance of being President than any individual Republican candidate.
"MADAME PRESIDENT! Hillary's Historic Win!" with sub headlines about the ticket and odd factors about the election. For example- "Close Virginia win seals Clinton/ Kaine election."
There would be similar Madame President headlines for Kirsten Gilibrand, Susanna Martinez, Elizabeth Warren and .
Puns about size would be possible in a Chris Christie victory. "Big Win!" or "Narrow Win For Big Man."
If Jeb Bush wins, expect the family to be mentioned. So it could be "Jeb! Another Bush in the White House!"
Paul Ryan would probably have a dull headline like "Ryan! House Budget Chair Wins Presidency." It could also be based on a slogan of the 2012 campaign.
If anyone's interested, here's a collection of 2008 election day headlines.
