Texas stuff.
From Pero's number I see that only 25% identify as liberal. The rest are centrist or conservative. Hard to swing left with a demographic like that.
I suspect that number might run around 30% on average. Perhaps the binary split between liberals and conservatives is not so binary...
There appear to be three ideological groupings. Makes sense, when any two of them join forces it makes the other 30% look batshit crazy.
