“up to one-third of Republicans are ready to call it quits as members of the GOP”
I already have. Registered as Libertarian.
Even though I don’t agree with the foreign policy stances sometimes. If the Constitution Party would field candidates for congress and senate even if they keep losing, until a conservative party is formed, I would switch to them. As such, they don’t do much so I am staying republican just to vote in primaries as my state is with closed primaries. Even then, I write in names.
