The one mistake Reagan made (and he later said he regretted it) was granting amnesty in 1986. That act turned Calif from the state which put Reagan in office into today's Mex-a-fornia. Now the current crop of re-pubicans, led by Juan McCave and Lindsey Grahmnesty are looking to do the same thing with the rest of the country.
As for me, no more voting for the lesser of 2 evils. There's either a conservative on the ballot or I stay home.
