Stopping every Republican except Nikki Haley who is as RINO as you can get appears to be the media’s goal. However, no matter who the Republican candidate is I’ll vote Republican. As bad as Halley is she’s still better than any Democrat. Trump is not my first choice, but the time to settle this is during the primaries and if he gets the nomination he’ll get my vote.
There are three problems that are related to Trump. First is the Democrat cheat machine that is alive and well in GA, PA, etc. Atlanta is owned outright by black Democrats, and no matter how the Democrat party screws them they will vote Democrat. Then he has to get a sufficient margin to break their cheating. Second there are a lot of real as opposed to imaginary Democrat voters who would crawl naked over broken glass to vote against Trump. Young college graduates with less sense than a cockroach, but with a vastly inflated opinion of their own worth and wisdom are just one example of these. Third are the Republican never Trumpers. They need to get their heads out of their nether orifices and wake up to what another Democrat administration would do to this country.
Your 3 points about a Trump candidacy are good but really they apply to whoever the GOP candidate maybe a little less with Haley but not much.
