@blatham,
If there is evidence that was unearthed as part of the Russia investigation that Trump or any of the people in office have broken any law, related to the election or not, I would expect that every single American would want to see them tried and put in front of a jury. The jury can decide if they are guilty.
That's true of any party, position, etc. If a law was broken, then the trial should occur. That's how our nation works.
Fact is that from all appearances, Mueller is operating under his special counsel mandate. To pursue matters related to the 2016 election and Russia's influence on it, and if there was any conspiracy with the Trump campaign. If during the course of that investigation, he were to say uncover Russian money laundering (for example) then I expect that he would follow up on that crime (because that is ALSO in his mandate). Especially since that puts our President in a possible blackmail situation.
What American wouldn't want this investigation to continue?
IF Trump is guilty of something and he gets impeached, the Republicans get Mike Pence whom, I believe, is in better alignment with what they want.
