The DemocRATS are living in the Stalin/Lenin Zone and they aren’t having any problems raising money. The morons running the GOP believe that they have to be middle of da road “moderates” to get people to like them. Morons. The only thing in the middle of the road are yellow stripes and dead skunks.
Our national parties, and their state affiliates, engage in a battle to pick up followers from the factions. Sometimes a large faction will shift from the Demos to the Reps, or vice versa. More frequently small factions do that without being noticed.
There is a fringe around the poles ~ virtually depopulated. it is not a middle filled with undecided voters.
