Complete waste of time. Regardless of what they say in public, in private their goal now is identical to McConnell's stated goal in 2008 - make Trump a one-term president.
I think this is where Trump’s dealmaking skill will come into play. He will find ways to neutralize/co-opt some Dems, and some RINOs. As long as he sticks to his agenda, I have no problem with that.
Our job as Trump’s citizen bosses is to make sure - insofar as we can - that Trump fulfills the most important elements of his (our) agenda: secure the border, stop terrorist immigration, dump CommieCare, cut taxes and regulations, appoint constitutionalist justices.
It can work. Good selection (which we know Trump is good at) and constant fawning.
