This is why they impeached Trump - he was asking Ukraine to make up some shit he could tout like this. They refused, so they had to go with a computer store owner who's legally blind but he's pretty sure these are hunter beidne's machines.

I like this take:
Giuliani's latest B.S. Ukraine smear failed. You can thank the Trump impeachment for that

Excerpt swipe:

To quickly recap the latest in Giuliani's impotent machinations: Steve Bannon, the former Trump strategist currently indicted on federal money laundering and obstruction charges, tips off the New York Post that the former NYC mayor has had in his possession what they claim are emails from Biden's son, Hunter Biden. Giuliani's story of how he got these emails is, to put it charitably, implausible. He says they were obtained from a computer supposedly left at a Delaware repair shop which the owner then turned over to him, for some reason. Perhaps a likelier explanation, as New York magazine's Jonathan Chait suggests, is that the emails may have been sourced from Russian agents that Giuliani knows.

The emails, which have not been independently verified, purport to show the younger Biden trying to set up a meeting between his father, who was vice president at the time, and executives at a corrupt Ukrainian energy firm, Burisma, where he served on the board of directors. Joe Biden's schedule shows he did not attend such a meeting, and the campaign says the Post didn't ask for comment on that allegation. But this is supposed to be evidence that Joe Biden is corrupt.

There's every reason to be suspicious of this weak attempt at an October surprise. It's important to remember that Trump got impeached because he tried to conjure up false evidence for these same bogus accusations by blackmailing the Ukrainian president into announcing a fraudulent "investigation" into Biden.

Moreover, it's a matter of record that Joe Biden's only involvement with Burisma was working with international authorities to fire a corrupt Ukrainian prosecutor who had failed to investigate Burisma. So even if there was an effort made by Burisma to corrupt Joe Biden, it failed. The emails, even if they're real, just prove he refused to get involved.

And so the efforts to pump this up into a big deal are failing. But without impeachment, there's a very good chance that Giuliani's gambit would have worked as intended, which is to flood baseless insinuations across the mainstream news media, including the New York Times.
