I've heard you say that. And it may even turn out to be true. But tell me, why would Frist and other Republican leaders do all of the political damage that they're doing to the party by chumming up to the likes of Kennedy to try to pass legislation to appease illegal aliens? It doesn't make sense if they're not actually trying to pass something. If your theory is true, why alienate the Republican base just to get no bill passed? Why not champion a get tough border security bill to let the Democrats crap all over it? Then it will make the Democrats look bad in November for being so weak on national security.
I think they want to snatch everything away at the last minute, like snatching food from a dog's bowl, so it will snarl at you and show you what he is really like.
When this bill stalls in committee, you are going to see illegals marching in the streets again, flush with support from the Democrats. The public will react in horror, and vote against Democrats for their support of lawlessness.
