What’s truly F’ed up is how big of idiots the GOP base voters are on this issue. There are in fact methods that would cut illegal immigration dramatically (mandatory e-verify, pumped up employer-level enforcement, and a bunch of related initiatives) but b/c their caucus continues to be the sad little slave of the low-wage-business-lobby, they just keep not doing even very basic things that would reduce illegal immigration.
(Note: I don’t support doing any of these things without an overall framework of comprehensive immigration reform including a path to citizenship, but the fact is, for voters who really want to stop illegal immigration, there ARE options, and somehow sickly, laughably, they just KEEP GETTING FOOLED and having their animus redirected into the farcial wall concept.)
