Those denouncing Trump forget he is the weakest newly elected GOP president in modern times. Trump’s polarising nature rules out his popularity going up that much.
His erratic nature means that his administration will perform poorly because those he appoints to make up his administration, all 4000 of them, do not know what Trump wants because that changes every day. Trump will have to arbitrate all disputes within his administration.
Congress will desert him as soon as it hurts their re-election chances in 2018 where a great many Republican Senate seats are up because they won back the Senate in 2012.
Trump is even weaker than average because a good part of his base do not otherwise vote in elections or they are registered Democrats. This makes his disgruntled base less of a threat in the 2018 Republican primaries.
Trump can only afford to lose 2 Republican senators. The Democratic Senate caucus will be united because opportunities if they can only pick up two Republican votes in the current Senate.
Trump will be an inept President but more socially liberal than any recent GOP president. Protest that.
Before you start on the fact that Trump won the electoral college but not the popular vote, remember the John Kerry to this day believes election fraud in Ohio deprived him of the presidency in 2004 despite losing the popular vote by about 3 million votes. Winning Ohio would have flipped that election.
