Who is left for Sessions to flip TO?
And if the House actually files articles of impeachment based on Session's testimony, or based on other testimony, or based on Trump's tax returns...then what?
It's not like the Senate is going to go along. So NOTHING will happen, EVEN IF the horribly unlikely circumstance of House impeachment happens. And the gerrymandering and vote-suppression nonsense will continue, and be blessed by the GOP-packed federal courts (there was a REASON that they refused to bring ANY of Obama's nominees to a vote - not just Garland), and we will no longer have a Republic at all, save for the name and the trappings. Trump will essentially start ruling by executive order, since he knows he won't get anything through the House, and this will be blessed by the GOP-packed courts to the point where Congress becomes irrelevant, and Trump declares himself Fuhrer.
The whole charade is crumbling before our eyes. The American experiment has failed. I am so depressed.
