Unfortunately the GOPe so abandoned their supporters that they lost credibility with the voters. They failed to oppose the gingerbread man on nothing in fact going along or supporting his agenda. The sole thing they did was not approving one appointment to the SC when the writing was on the wall i.e. Hitlery was not a winning candidate.
One likely scenario I see playing out now is that the support for Hillary will collapse at the polls. Hillary is becoming kryptonite and any dem associated with her. She will affect races below the presidential race.
There maybe a noticeable number of dem voters that will not show up at the polls. That means they will not vote for any lower races such as senators, representatives, governors, etc. Republicans and Independents on the other hand, will show up at the polls and vote. Turnout will be the key. If this scenario plays out, don’t be surprised to see the GOP retain the senate.
