No kidding
Third parties are ALWAYS a mistake
EXACTLY! You drastically change the part you belong to, not form a new one.
If you are not prepared to win across the board, then you have to put up with the pukes in the old party you are seeking to abandon.
The basic idea in forming a new party is always to cleanse your own political environment of deviants ~ at the moment the Republican party has a lot of deviants who need shed. If we really wanted to lurch to the left and vote for Democrat BS we'd just vote for Democrats.
