Massive illegal immigration is why.
It's not either-or, but both. Starting at least in the Wilson Administration,
Mo-o-o-o-o-o-o-o-o-o-o-oderate Rs have worked as hard or harder to keep conservative Rs out of office than they have to defeat Ds. I wish that were hyperbole!
Illegals voting has hurt the Rs as well, but CA Rs cannot, by themselves, change that.
CA Rs can stop their fratricide.
