IIRC from reading Frist's comments and proposed legislation, it's basically a McKennedy redux being introduced by Frist at the behest of the RNC to try and salvage an amnesty while maintaining the appearance of having addressed the problem (which it does not).
If he's too stupid to come out with a forceful, strong bill here, he's too stupid to be president. I think he's an intelligent man, but he's a wuss, politically. One thing I admire about McCain is that whether I agree with him or not, he comes out and says what he means, for the most part. I wish there were a conservative running for president who behaved like one AND made me think he wouldn't go wussy when he got to DC. But seeing how even Reagan went wobbly on a number of things important to me, I don't hold much hope.
