Most likely they will. You have to consider the following.
Right now Republicans have to deal with the following.
1. Their President is a walking meme who would rather post on twitter all the time than do anything to help their own tax cut campaign
2. Said Meme President has an astronomically low approval rating where the only people left that support him are essentially loyalists that worship him and never question anything.
3.Moore got assblasted in Alabama because he thought Trump's endorsement and the fact that Alabama is a hard Red state would ensure his victory.
4. The Russian probe is still ongoing and recently got Flynn talking
5. Now that the FCC, currently run by a Pajeet acting like a smug child over what is essentially the corpse of the internet, has started the process of killing NN, everyone in America is going to be pissed and aiming right at the Republicans.
To put it simply, right now the Republicans have to make a choice on whether to stay their course, or make an attempt to save their skins by going against the NN repeal, against Pajeet, and against Trump in order to protect themselves from a growing angry American public.
Already people are forming lawsuits against this, so while Trumpfags gloat and act like morons on /v/, it won't last long.
The funny part will be that they'll find some dumb reason for why NN got saved, probably Jews or SJWs, or the like.
