Conservatives began to believe that we could be as immoral and obnoxious as the left because our goal was noble. (The ends justify the means) "The ends", Federalism, less spending, lower taxes, less government, have all faded away and been replaced with a raging desire for revenge at any cost.
Good post. I highlight the above because I think maybe you've over-thought it a little. For conservatives in general, I think what you're seeing is maybe not so much due to adoption of Alinski tactics, as it is due to a lack of understanding of our own philosophy.
Alinksi tactics are designed for political hyenas who prey on those people and ideas that are least easy to defend. They're not concerned with political principles
per se; they're designed to create 'victory' by destroying the opponent. Alinski tactics use people's own manners and principles against them, and they're really not concerned about the collateral damage of 'victory.'
I really don't see that sort of cynicism or political focus among conservatives. Rather, what I generally see is frustration and anger at being unable, for various reasons, to make a cogent case for conservatism, much less to stem the tide of the authoritarian left.
And so we fall into the trap of trying to destroy our opponents in the same way they always seem to destroy us. Unfortunately, they understand what they're doing and why, and we're just reacting to it.
Trump's central political insight for the election was to recognize and exploit the frustration and anger of regular people against a system that really is broken. Perhaps a demagogue was the only sort of candidate who could have done that. Unfortunately, as we seem to be seeing, demagoguery is not a good strategy for governing effectively in a system like ours.
