The Congress should try and pass HR4437, or something very similar to it. It will help Republicans hold the Congress this November. The GOP needs to stay away from anything that looks like it might be considered amnesty. Let a temporary foreign worker wait until after the November election. I think no decision at all, is a bad decision.
I think Frist's bill is a very good "compromise" bill. It lands between Kennedy-McCain and 4437--only far closer to 4437.
If the Republicans had any backbone at all, I think their strategy should have been to force 4437 through, and when they met opposition, to offer up Frist's proposal.
That at least gives us no amnesty (or amnesty by another name), a fence, increased number of border guards, and fines against employers who hire these criminals.
