The end of Republicans?

I wonder...if Trump's performance continues on its current course, what will become of the Republicans?

As a group, they seem so hell-bent on taking power that they've forgotten they're in a democracy.

During the election, they couldn't unite behind someone with any experience at all, they had to resort to presenting a buffoon as their candidate.

Now that the world has seen just how bad Trump's presidency has been, how many of the Senators and Representatives voted in on his coattails will be unceremoniously booted out at the next elections?

Were that to happen, the Republican party would still exist, in some form or another...but would it still have any viability?

Perhaps it's time for the Republicans to split into their actual factions and the US to become a multi-party system.
