In the upcoming presidential election, two issues are more important than any others: repealing Obamacare and halting illegal immigration. If we fail at either one, the country will be changed permanently.
Taxes can be raised and lowered. Regulations can be removed (though they rarely are). Attorneys general and Cabinet members can be fired. Laws can be repealed. Even Supreme Court justices eventually die.
But capitulate on illegal immigration, and the entire country will have the electorate of California. There will be no turning back.
By the way, Ann goes on to conclude that Bachmann and Romney are the best on illegal immigration, but that only Romney can win.
