Of course the system gives one party an advantage...the party that finds itself consistently losing elections, then blaming the elections instead of their own shitty, failed policies, candidates, and ideas. Without the Electoral College and if there was fair representation in the Senate and House, the GOP would have no control. None. And rightly so because they didn't earn it.
You seem to think they earn it by virtue of simple existing. That's entitlement. If states couldn't draw their own federal districts, the GOP's deficit in the House would be much greater. Partisan gerrymandering is the only reason the GOP remains relevant because they have no policies, no record of success to celebrate.
No they don't. Georgia is a perfect example of how Republicans are not benefitting from people moving to red states.
Speak for yourself. Policy is all I care about. The GOP and Conservatism have no coherent policy. They are fascists, as we see right now where they refuse to accept the results of an election because it didn't go their way and they couldn't cheat to win it.
