All the others would have won all the states that Romney won in 2012. Maybe Cruz, Rubio or Jeb might have also carried Florida, but other than that, I don’t see any of them flipping any other 0bama won states.
Obviously other candidates could’ve flipped Iowa and Ohio too. For how far they went GOP this time, analysts are saying those may no longer be swing states for the Dems.
Rubio, Kasich or Cruz all could’ve beaten Hillary. None of them would’ve had the albatross of “the tape” hanging around their neck. Rubio and Cruz would’ve had extra appeal with latinos and the Christian/Mormon base. Kasich would’ve had the rust belt appeal. Kasich might have undone himself with a weak campaign like Romney though, and by driving away too much of the conservative base.
This was not a hard election to win. Hillary was a terrible candidate.
