Impeachment does nothing.
It simply is a recommendation for the Senate to have a “trial”.
A democrat Senate would do nothing.
But, even assuming a republican senate, it would still have to be a super-majority, iirc, to convict.
Impeachment will not result in a conviction, but Obama has broken his oath to protect and defend the Constitution and, in fact, is attempting to subvert it where ever possible. Calling him on the carpet in the House would seriously shift the debate and infuriate the narcissist.
I don't think the Senate can ignore an impeachment. It's not a bill that Harry Reid can refuse to bring to a vote.
Besides, Chief Justice Roberts presides over the trial in the Senate, not Reid.
