@revelette1,
I don't have any stats, but I believe that Edgar is correct.
The Democrats have ceded the entire state to Republicans and Libertarians. In West Texas there aren't even Democrats listed on the ballot for local offices.
Even if Texas Democrats wanted to vote for Democrats, they can't. If someone does want to run for local office, then they
have to be a member of the Republican party. If you want a say in who actually represents you locally, you have to vote in the Republican primary.
It completely skews the numbers, since Dems only come out to vote in national elections.
