Well, it's worked for the past 20-30 years...sarc/
This whole thing may be the biggest misdirection-coup I've seen in decades. The whole issue, that NO ONE has touched or attempted to solve before - is all Bush's doing/fault - Bush, the only man to take it on.
Reminds of Howard Roark in Fountainhead - in his defense speech - about the man who first invented fire - "He was probably burned at the stake for it - but thereafter, man had fire"
Technically, the 'whole thing' started in 86, cause there were NO illegals immediately after Simpson Mazolli passed. 60% of the 12-20 million currently in country arrived between 86 and 2000, and 40% - 5 to 8 million - have arrived since W took office, since his SOU address when he laid out his guest worker agenda.
So, while he's not responsible he certainly has made the problem worse, IMO.
However, he's not beyond redemption - if he jumps on board the Sensenbrenner Bill bandwagon I'm willing to let bygones be bygones.
