I was a lifelong Republican. I re-registered as "not affiliated" with the rise of the Tea Party, but still voted Republican 95% of the time.  This was the first election where I did not vote for a single Republican.  Many Republicans were and are totally horrified by Trump and the capitulation of most Republican politicians to supporting him, including many who had it right before he won the nomination.  Many Republicans joined a movement called #NeverTrump. Some, like George Will, publicly left the party.   I am currently barely on speaking terms with some in my family (all loyal Republicans) and a couple of lifelong friends. Believe me, losing these relationships at my age is not easy, but I find I  cannot even engage in conversation with them, so simply keep my distance.  I feel that they have betrayed their stated principals, as christians, as "patriotic Americans", as official Republicans.  Kag and I and many others did not support Trump.  A viable third party is needed now.
