The GOP is afraid to turn on Trump because they are afraid they will loose his supporters if they do, when the next elections come around. However, by supporting Trump, they are also eroding the moderate base in their own party and driving away independents too. The GOP has yet to realize that they have set a trap for themselves. They are caught either way. The only way to salvation is to dump Trump, take their lumps in the next midterm and Presidential elections and purge their party of the extreme right wingers who have so damaged the party's credibility. It may take years to rebuild the party but it is the only way out of the mess they have created for themselves.
