Judicial Watch, pointing out 11 districts in California that had turnout over 100% in 2016.

California has roughly twice the population and electoral votes as Florida where I live. And yet despite being just under 50% Republican, in presidential elections Republicans there might as well not even vote. As huge as California is, I've often wondered why it hasn't broken into two states, to give conservatives there the representation they have clearly lost.
Or at least proportionately split the electoral votes there, instead of making California's electoral votes winner-take-all.

Aside from, y'know, the lack of representation on how their high taxes are spent on illegal immigrants and the homeless, and sanctuary cities they never asked to be a part of. Hence the exodus of middle class voters to Arizona, Colorado and Nevada.
