At this point, with the amount of information that's out there. I think the universal in unbiased thing to do is go against Trump. Rebranding republicans as the loud, obnoxious, physically violent party is detrimental to everyone. No one, no one, no one should let their vote amplify the voices of the freaks and losers that are represented by Trump's platform.
If you're a republican, you should be insulted by Trump's campaign success. He's every criticism of the party distilled into an orange hideous troll man. He's a violent, racist, lying narcissist, who runs on bullshit and bravado, and if you support him, your either an idiot having a tantrum, or someone willing to have the entire republican platform demolished for a "win" for team Republican.
