Most certainly, they are.
Furthermore, for poll purposes, who the hell is going to publicly admit to being a Trump supporter in today's climate?
That said, I'm afraid that they've got the Trump Hate Train at full throttle, and every moron over 18 will be voting anti-Trump in 2018
We're f##ked.
Pres. Trump won't be on the ballot in 2018. The Pubs who didn't keep their promises will be. I know I won't be voting for them.
Pres. Trump is a President without a party. The weak Pub establishment supports him in name only. The conservatives in the Pub party support him, but it's been made painfully clear that they are a minority within the Pub party. I expect the Pubs to lose a lot of seats in the House and maybe pick up a third of the seats they should have in the Senate in 2018. The conversion of the Pub party into a minority party will be completed in 2020. Pres. Trump will win re-election if he decides to run.
It's a mess. The Pubs have controlled the govt. only 4x's in 100 years. They could have put any legislation in front of Pres. Trump on health care, tax reform, infrastructure, entitlement reform, immigration reform, etc. and they can't get anything done. The Pubs have made it clear they have no core values, no party discipline and should not be a majority party.
