The Congressional Republicans' approval rating stands in the low 20's. Which means that about 80% of the people disapprove of them.
If we go with the usual figures of Democrats and Republicans each claiming about 40% of the voters, and the remaining 20% being independent, we should come out with a figure of 60% disapproval (40% Dem plus 20% independent. Assuming, incorrectly, that all independents voted Democrat Which will just make my point that much clearer).
Instead, we have a disapproval rating of 80%. Where did that other 20% come from? You got it: the Republicans have managed to piss off half of their voters! Alright, hey! Alright, good job guys! Let's go get some shawarma!
If ever there were a time to start a third party, now would be it. We have 20% of the Republicans pissed at the party. If we can pick up even half of the independents, we're already starting with 30% of the population. Pick off some more of the Republicans - which shouldn't be hard once those on the fence have a place to go - and some more of the independents, and we have a very competitive Party.
And John Boehner, Mitch McConnell and all of the rest of the cowardly Republican rats can go down with their neo-liberal ship.
