Yes, and besides self-preservation, there is anger brewing among Republicans. This isnt just about President Trump anymore - the Democrats have stupidly declared war on the Republicans.
Regardless of how they may feel about Donald Trump, I suspect Senate Republicans cant wait to shove this right back in their ugly Democrat faces.
Correct. They have to look to the future when a Republican President who will likely be more to their liking than Trump will likewise face a sham impeachment at the hands of loony radical Dems.
Romney or Jeb! would have folded their tent and resigned long before things got to this stage. They have to think about that and then play the long game, regardless of their personal feelings about Trump.
