I have no doubts they are going to drag this out until much closer to the election so they can impeach him at some critical moment to get media headlines to sway people into thinking Biden is just as bad as trump.
This was what was so crazy about Trump vs Obama. Obama had such a a big target on his back, he had to act unimpeachably. But Trump was pretty much impeachable from the start.
They went after Obama for silly things like mustard and suits and putting his feet on his own desk [yes, these were actually things they got mad about] When they saw that it wasn't getting traction they stepped back. They knew if they impeached Obama they'd never get another Black vote ever.
They were after Bill Clinton from Day One. They pushed the Whitewater probe before he entered office, and tried to make 'Travelgate' [Clinton's team fired some White House staff without realizing they had tenure. ] Vince Foster was a Clinton family friend who committed suicide after the election. The GOP said he was murdered.
Because it was never just "one little cable network". It was a Murdoch outlet with a ton of economic and political support from the major power players of the US right wing high society from day one.
It was never not designed to monumentally sway public debate and political policymaking.
I absolutely believe if they could have made the smallest thing stick they would. They probably would do it a second time before the election if the first one fell through. "LOOK AT BIDEN! HE HAS TWO IMPEACHMENTS AS WELL AND JUST AS MANY SENATE CONVICTIONS AS TRUMP"
The point isn't to actually impeach him, it's to make a big media circus that frightens and confuses voters. They want the biggest news story in the days leading up to the election to be "Biden lookin sus" as opposed to Trump's criminal history or the state of the economy, because that's their best shot at pulling votes away from him.
