Yeah, as evidence in going after aspects of the Ukraine thing? Absolutely use them as evidence, show the pattern of behavior, etc.I think there's a third way, and it's exactly what Schiff has laid out, which is you don't do all the things, but you do the other things that lend credibility to the Ukraine scandal, which I think is genuinely the worst of them all.
I think he basically put it like so.
1. Trump attempted to get Russia to provide him information on his opponent.
2. Trump obstructred justice over the investigation into whether or not he broke the law doing 1.
3. Trump attempted to get Ukraine to hurt the person who at the time was the leading candidate to be his opponent next year.
4. Trump and Barr (who was implicated in 3) conspired to prevent 3 from coming to light when a whistle-blower complaint threatened to blow the lid off the whole thing.
Just don't put them in the damn articles you're charging on or you're gonna have the scattershot problem all over again. You can just charge him later!
