I hear ya' Gadget and certainly mirror some of your thoughts.
With the House only being only 1 or 2 seats over the majority mark there will be little to worry about; Specifically, crazy laws being passed. Of course the House controls the purse strings so that means probably little to no money for the wall.
With the Senate picking up 4-5 seats this really cements the ability for Pres. Trump to work on Treaties, Trade agreements, Federal judges, etc. It is historic that the party of the President picks up Senate seats.
Well remember, Trump is the "great" negotiator. Not unlike former Pres. Clinton in 1996 when the House went GOP, lets see how well he negotiates.
All in all, I am A-OK with this mid-term election results. Heck Trump will need something (the House) to run against in 2020.
