President Mitt Romney (R-MA) / Vice President John Cornyn (R-TX)
Businessman Donald Trump (D-NY) / Fmr. Governor Tim Kaine (D-VA) ✓
Boots are on the ground in Iran and/or Syria and the Great Recession has only gotten worse. Conservatives attack Trump for his personal scandals, and Trump faces an uphill fight in the primaries from people in the Kerry administration's orbit (maybe a Senator Obama who ran with Kerry in '08), but the anti-Trump vote is split and an endorsement from Senator Hillary Clinton really helps. In the election, voters just want Romney out.
