The only way we don't get a President Trump is if John McCain wins in 2008.
Trump probably would have primaried Romney into oblivion in 2016 if Romney had won in 2012.
If a Trump primary succeeded against Incumbent President Romney, Hillary Clinton is elected President and Donald Trump never steps foot in the White House, though Clinton likely loses in 2020, making three consecutive one termers in a row.
Nah, Russia really had it out for Hillary (and possibly Biden too), they would have helped Trump get over 270, as they did IRL.
