It sounds like you're trying to be thought provoking, but the flippant answer is also the correct one: it depends if at heart you are really a Democrat or Republican.
If at heart you're really a Democrat, then you don't care a whit about intellectual honesty or consistency, all you care is how you feeeeeeel at the moment.
So you'll eagerly condemn in Republicans what you happily accept in yourself, etc.
Republicans by contrast are burdened with the need to be both honest and consistent with our morals and ideology.
On your question of "nullification" Democrats were always the party of nullification, and remain so today.
And were the roles reversed (as in civil rights laws) Democrats would take nullifiers to court and throw them in jail, but somehow that hasn't happened with Democrats' "sanctuary cities".
Do you even wonder why?
Hopefully you’re aware that Ronald Reagan was at one time a Democrat. Did Mr. Reagan change in some radical way, before joining the Republican Party?
He may have matured a bit, and certainly became more knowledgable, and much more experienced. But his values apparently remained largely consistent; as he put it (quoting from memory), ”I didn’t leave the Democrat Party – the Democrat Party left me!”
Simply put, today’s political parties are NOT the same parties that existed 50, 100, or 150 years ago. The names may not have changed, but the foundational beliefs certainly have. (Just to emphasize that point, here’s a bit of historical trivia: Karl Marx supported the Union! ;>)

Actually, I may well have been voting conservative longer than you’ve been alive.

Come, now – if that were true, there would be no debates on FreeRepublic, and no competing Republican candidates in the party’s primaries.

Perhaps you should reread that post. When I lived in Colorado, it was the Republican sheriffs in the State that refused to enforce (i.e., ‘nullified’) the new Democrat ‘gun control’ laws. The same thing is happening in Virginia, even as we speak. A more accurate description (obviously still subject to debate) would be that some “constitutionalists” or “strict constructionists” support nullification, as do some scoff-law Leftists. As I believe rockrr noted, it’s not a ‘cookie cutter’ issue.

Perhaps you should ask someone who’s a Democrat. Back when Californians were suggesting that their State secede to get away from the ‘Bad Orange Man’, I believe I posted here on FR my opinion that, if that ever happened, Nancy Pelosi and the Democrat Party leadership would be the first to demand that the US military invade the State, without delay, and shoot the ring-leaders. (As noted, the parties have changed! ;>)
