Then Republicans will run Hispanics. Cubans usually vote Republican. Mexicans whose families have been here for along time are more assimilated and aren't in love with illegals.
And you are assuming the current Democratic coalition will remain together -- that African-Americans, Latinos, Asians, gays, feminists, labor unions, and White liberals think alike and won't come into conflict.
The real world disagrees with this wish-casting.
Actually, let me modify my response. I’m really talking about conservatism not a political party.
Yes it is possible for some future GOP 2.0 to do OK with Hispanic voters — But it will do so by moving hard left on just about everything, particularly borders, immigration, and free stuff.
It is conservatism that will be finished on a nationwide basis. It will be as dinosaur dead as it is today in Reagan’s home state.
