Using their own approach, all we have to do is set up a useable version of eVerify, and fine employers $100,000 for each violation of the immigration law, and the illegal problem will melt away in weeks. That approach has the advantage of being anti-business, like Democrats always want, and it could potentially bring the revenue they want to create their Utopian state. Everybody wins (except they lose the huge pool of potential voters, which is their ultimate goal, as everyone with an IQ above room temperature knows).
The GOP also needs to learn to exploit the fractures among the very volatile factions in the democrat camp.
