Years ago Pelosi blocked the House from launching impeachment hearings of George W. Bush and recently admitted she KNEW the Bush administration was lying about Iraq at the time.
Up until recently Pelosi fought against launching an impeachment inquiry of Trump (which should have started over a year ago) until she was dragged into it. Up until then, she was his foremost enabler by resisting it.
Then Pelosi successfully limited the scope of the impeachment inquiry of Trump to Ukraine. By limiting the scope of impeachment she placed a poor political calculation over the oath she swore to protect the Constitution.
In the same week as articles for impeachment were passed in the House, Pelosi and establishment Democrats gave Trump some of the biggest wins of his presidency (the USMCA Trade deal and a new defense spending bill that increases spending by $22 billion, gives Trump money for his border wall, and formally establishes Trump’s “Space Force”).
Now Pelosi seems to think that delaying sending the articles of impeachment over to the Senate will somehow give her leverage over how the Senate will conduct the trial. I’m not sure why she believes this gives her any leverage AT ALL. I’m sure they’d be HAPPY if she NEVER sends it over. The longer she delays the more public support will decline, and the better Republicans will be able to frame it to their advantage.
