Simply look at California. Used to be great state, conservative and a leader. Now it’s broke and a one party rule landslide blue state.
Arizona is now becoming a competitive state. It once ran up GOP presidential majorities so huge the Dems totally wrote it off. In the once dominant GOP West, we'll soon be down to the tiny electoral college states of Utah, Wyoming, Idaho, Alaska, and Montana (and even Montana is becoming competitive).
This is all largely the result of mass migration of immigrants into these states. Those immigrants not only vote leftist, but send upscale white liberals fleeing from their traditional strongholds in LA and the Bay Area into CO, AZ, NV, MT, etc.
The same thing is happening in Texas, but more slowly since the whites there are so overwhelmingly conservative. It'll take more immigrants to turn it blue than it took in California, where a sizable minority of the whites were lefties. But around 2016 or 2020, Texas will likely fall to the ‘Rats.
Now, this will cause some turmoil on the ‘Rat side, with blacks feuding with Latinos, both groups feuding with homosexuals, and so forth, but it won't help conservatives any. All it'll mean is that conservative whites sit by and watch the various identity factions of the ‘Rat party fight it out for turf. We might get some guilty pleasure out of it, but no wins. On election day, they'll all vote against whitey, and then all go back to feuding among themselves afterward.
Perhaps every once in a while a Rudy Giuliani type Republican, who's liberal on most domestic issues, will win. That happened in New York City when black mayor David Dinkins became so racially polarizing that normally Democrat voting groups like Jews & Puerto Ricans voted for Rudy out of self-defense. That helped a little, maybe, on crime issues and so forth, but it didn't change the overall liberal drift of the culture and it didn't change the Democrat dominance of the city one bit. NYC still elected an overwhelmingly leftist ‘Rat city council and continued to vote ‘Rat big time in state and national elections.
Eventually, some of the mushy white moderates who voted for Obama this year will realize that the rainbow coalition doesn't include whites and will drift back to the GOP, but by then it won't matter. The Republicans will be down to a few mid-sized southern states and a few small states like the Dakotas and Idaho.
The change in our immigration laws in 1965, combined with allowing millions of illegals to sneak in, is about to make us a Third World nation.
