Democrats are no longer viable this election.
Entirely false. Polls show that this election actually favors Democrats.
The Republican party is completely divided right now between the establishment and the anti-establishment (Trump supporters). Hence you have yelling matches in debates, the GOP trying desperately to get rid of the candidate most likely to win the nomination, and Romney throwing everything he's got to try to bring down Trump. Ultimately, all this fighting will lead to poor Republican turnout in the GE no matter who's nominated, as the establishment and anti-establishment are unlikely to want to vote for each other's candidates.
Also, Trump's as hateful as it gets, I don't know how anyone could see otherwise
