No, let him finish destroying the Republican Party in office. Can you imagine how fantastic the midterm election would be?
At this point, considering the temperament and mental (in)stability of this candidate, this issue transcends traditional political partisanship. His presidency would be a threat, not only to our country but potentially the world. If he made it into the executive, then as soon as he threatened human rights, constitutional rights, or international security, he should be removed immediately. I find absolutely nothing positive about a Trump presidency; not even the destruction of the Republican Party would be worth that damage.
