I don't have to "claim" that both Tim Scott and the republican party leader Donald Trump, two of the current clowns running for president, have espoused "bomb mexico" as part of their platforms. They both have. It'll be interesting to see if the random other folks running for president from your party run away from that part of the platform or towards it. Considering that Ron Desantis has seemed to have adopted a platform of "whatever trump does I'll do it even more" I assume he'll soon be adding "bomb mexico right after we bomb my state's biggest employer and tourist attraction" to his platform.
But to be fair, you're right. To claim that the republican party has any sort of coherent policy priorities beyond "hate people that aren't cis het straight white male folks" is probably giving too much credit to the modern day republican party.
I'm curious what your "exalted thinkers" on your bookshelves think about all this?
