In June 2015 Trump had a negative rating with GOP voters of 67%, it is 18% now.
Clinton, on the other hand, has shown that the more she campaigns, they less favorable her ratings.
Frankly I would rather be in Trumps shoes then Clinton on the Unfavorably issue. Trump has the potential to win people over during the campaign. Clinton's only hope is to make people hate Trump more then they hate her.
But I can tell you will be doing everything you can to help Clinton do that,
What exactly is “principled” about actively working to elect someone who is 100% opposed to your self proclaimed values like Hillary Clinton?
I will continue to actively work to get someone other than Trump to be the Republican nominee—anyone, but preferably Cruz. If Trump should become the nominee, I cannot actively support him, since I regard him to be a detestable human being, devoid of character, as well as being untrustworthy on the issues. Whether Trump can do enough to placate all the conservatives he has alienated and disgusted, so that we could hold our noses and vote for him on November 8—that is up to Trump.
