If it is proved that Trump himself colluded with the Kremlin to violate US laws I would want it taken care of and not just brushed under the rug. Most Republicans and Conservatives would want that. Yes. I would find it disturbing if Trump was guilty of criminal activity while running for President. But I'm not disturbed at all if there's no proof. It's just "fake news" at this point.
Obviously, Democrats see their law breakers in a different light and don't want them prosecuted no matter what they've done. That was proven when Bill Clinton was not convicted of perjury after he was impeached and it was proven when Marion Barry was reelected after he served prison time for drug trafficking.
