Yeah, well, the Senate isn't going to stand for an impeachment either way, but if Trump were to be impeached over the transcipt that's been released today it'd be his own fault. Total and utter lack of situational awareness. He did indeed ask a foreign head of state to launch investigations into the business affairs of the son of his most senior political challenger.
If that's what he thinks has always been necessary, he should have done it right away after taking office in order to avoid a clear and present conflict of interests.
The funny part is that what Biden did back in the day was not to lobby for the protection of his son's employer – he actually asked the Ukranians to ditch a prosecutor who tried to stymy corruption investigations into his son's employer.
Now, it's impossible for us to assess whether or not his son was somehow given an advantage here (e.g. a career advantage). On the other hand, it's quite possible that Biden junior simply went to his father a whistleblower and went like: Dad, I saw those guys break the law but no one wants to listen to me, what should I do?
I tried to be as impartial as I possibly could, but the fact as I see it is this: If you're in agreement with what Trump did, you're in agreement with a degree of corruption that actually befits Ukraine better than it does the United States. If that's what you're contented with, well, I admire your thick skin. But I find it perfectly plausible that even a hypothetical objective observer would find Trump at fault here.
At any rate, this is a futile offensive that isn't going to break the stalemate of trench warfare. Trump's followers are never going to accept the impeachement, and they cannot. Much like in actual trench warfare, too much blood has been spilled. And they've not forgotten (nor should they) highly immoral and probably illegal schemes like Obama's IRS campaign against right-wing groups.
Whataboutisms. Modern politics has become all about whataboutisms.
