Please elaborate.
As memory serves, "tea party" ire about Willard was pretty much universal throughout the 2012 election cycle. Constitutionalist ire against him was pretty outspoken during 2008 as well (though that was mitigated by the displeasure of the GOP-E candidate of that cycle, McLame). I can think of many, many people who didn't hesitate to use any and all means to skewer Romney during that cycle, such as this one:
Now we're supposed to be incensed because Trump does the same "genus" of thing as we did back in 2012? (Yes, a different species but definitely the same genus). I find it a bit odd criticizing somebody for mocking a figure whom I, myself, have mocked mercilessly.
Trump is, as you stated, a boor. Trump is, as many of us have stated, no conservative. I prefer to criticize him when he displays that boorish behavior toward an actual conservative.
I wish he wasn't the nominee. But he is.
