Republicans should back best third-party candidate
To this point, Donald Trump’s candidacy has been focused on the point that he is not Hillary Clinton. Finally, the Republican Party leadership is realizing that Trump is worse than Clinton. Trump insults and treats many people as worthless. He is not someone who should be running for anything, much less president.
The party leadership and as many key Republican leaders as possible need to meet and decide which third-party candidate on the ballot nationally is the best person to support, get that person on board, then quickly and with massive publicity support that candidate. At the very least, this is the honorable thing to do.
