Conviction requires a 2/3 vote by the Senate, 67 of more of 100 Senators. Presently the GQP controls 53 seats, the Dems 47. So the GQP would need at least 14 Dems to vote for conviction. That may be a tall order. However, if we ever reach the stage where the Dems are that compliant, it's pretty much all over for us.
But they don't need convictions. They'll just ignore the judicial rulings, as they're already doing, the DOJ will not do its job to enforce the rulings, and even if the Supreme Court were to rule against Der Fuhrer Schitler, he'll just ignore them too.
