Consider:
1) regardless of actual knowing collusion Russia interfered to help Trump;
2) Republican support for Ukraine is being undermined. By Russia;
3) Trump to this day refuses to unabashedly criticize Putin's invasion of Ukraine;
4) Russia seeks to influence our elections even now, in an effort to get Republicans elected to have a more pro Russian US government, or at least one that will not resist them.
1) Not quite; it was anti-Clinton due to her implying the 2011 Russian elections were rigged and that Putin wasn't duly elected. She made Putin her adversay, and the Obama admin handed Trump the worst U.S./Russia relations since the fall of the USSR.
First, Russian interference was a laughable drop in the ocean of political spending. It was anti-Clinton when it supported both Sanders and Stein, and it was anti-Clinton when Trump and Clinton became nominees of the two viable parties. It became exclusively 'pro-Trump' when Trump became the exclusive candidate with a chance of beating Clinton.
2) To the degree Repub support for Ukraine is less than effusive, it has diffuse grounds but recurring theme. Some have stupidly bought into the Nazi meme, while others oppose on grounds of tossing $ at a country with corruption problems. Opposition also springs from the folly of foreign policy in which there's not a clear U.S. interest (except proxy war), and risks another military misadventure, possibly catastrophic war with our treasure & blood on the line. There is also an anti-globalist strain of opposition. Avoiding military misadventure and globalism is a Trump residual and one way in which he transformed the party for the better. It's no coincidence the same Republican establishment that undermined Trump were the same cast of aging characters that virulently opposed Reagan.
3) Repeatedly stating Putin did not and would not have invaded on his watch is denouncing the invasion as wrong; there's no other way to interpret it. Frankly if I were Trump I'd state "I denounced white supremacists dozens of times - from the outset - even as the left kept demanding I renounce it. Why don't you all go fk yourselves until you learn how to accept 'yes' as the answer you're wanting?"
4) This is nonsense, erected on the wobbly three legs of assertions 1), 2) and 3). It wasn't enough the Obama admin handed off the worst post-Soviet relations with Russia, but that Dems former SoS and presidential nominee would pour gas on the relationship and toss a match for nothing more than to hold the presidency. If Trump was inarticulate or indecipherable in speech, it was against the backdrop of having no reason to trust a CIA, DOJ/FBI that were out to hang him using Clinton's depraved scheme as cover story, AND having to deal with the most nuked-up country on the globe in a publicly non-confrontational manner just as EVERY damned president does. The left talks as though Trump should have called Putin a lying cksucker and wrestled him to the ground at Helsinki, as if Obama ("cut it out", "flexibility"..."red line") or Biden would have done just that. Just as they talked a good game prior to fist-bumping MBS, shite changes when you're actually president and not a glib Senator or congressional. It gets real when the other guy has nukes, too.
