Unless he “rules” by executive order, any change he wants to make to laws will require 50 supporters in the Senate (60 if someone wants to filibuster). 54 Senators are currently Republicans, but 24 are up for reelection in 2016.
Will people vote for Trump and their Senator if the Senator doesn’t support Trump?

If you sort by 2016?, you can see what is possible in January 2017
– 5 senators are not running – 3 are Democrats (CA, MD, NV)… California and MD are safe Democrats that Trump has zero chance of winning
– 10 races are considered “possible to lose”, 9 are Republicans
– only 10 Democrats are running
Most optimistic case is Trump would face 56 Republicans, 13 of which oppose his agenda. The only way Trump gets anything through the Senate is with Democratic Party Support. Worst case is the Senate has Democratic majority of 55 seats and 13 angry Republicans. That’s enough votes for removing Trump from office via the impeachment process.
Of course, every House seat is up for election, so it is hard to put boundaries around what might happen there.
It’s a starting point – as the realities sink in, things will change. Maybe in two years, president Trump will have the clout to knock out incumbent Senators
If Republicans don’t outright lose the Senate, Chuck Schumer has lots of perks he could offer Republicans to switch parties and give Democrats control of the Legislative process
