Not only would that be super epic and historical, Trump would finally be able do the things he has wanted as President but has had his hands tied by a Dem run Congress. A Rep held Congress would mean no more stupid and wasteful impeachments.
Can it be argued that in the mid-terms Trump wasn't on the ballot, therefore the Dem party won Congress, but this time in all three houses, Trump is on the ballot and therefore Rep party will do much better?
The media sure underestimated the ire and passion of the tea party went it swept the Congress. Back when protests were considered dangerous and against their own interests.
