Coat-tails
Trump seems to have generated at least as much criticism from Republicans as Democrats, so there is a feeling that a newly-elected Congress will be as obstructive to Trump as they were to Obama. I don't believe it. I think Trump will win big and have significant coat-tails -- i.e a lot of Congressmen will have wins as a result of the Trump GOP brand. Some will win who would not have won without Trump. And that will percolate. GOP congressmen will see Trump as being owed. He will of course have to compromise with Congress, as all Presidents do, but that should work well to lead to well-considered legislation.
