This advice is useless because the elections were fraudulent and nobody is doing anything about it. Unless the GOP is going to stuff ballot boxes too they’re going to continue to be graceful losers until the demographics shift too far and it becomes irrelevant.
The GOP held 247 House seats in 2014. That was their largest House majority since the 1940s -- and yes, that includes the historic 1994 "Gingrich revolution" sweep.
Almost every immigrant group in this country turns progressively more CONSERVATIVE with each succeeding generation. This is the lesson for Republicans to learn. They already did, in fact. That's why you had George W. Bush running around speaking Spanish on the campaign trail.
