Agreed. They're hyper-sensitive to the "racist" label, even though it's so over-used that it means nothing today.
The pubs are in a fish-or-cut-bait situation--their constituents, the blue-collar workers, are getting hammered in the workplace and are looking for relief. On the other side, the pubs don't want to get labeled "racist" by the dems when they so much as clear their throats to talk about immigration. Throw in the pubs' efforts to win over the latino vote and you've got a situation that requires strong leadership, vision and a stiff backbone--something the pubs are seriously lacking. It's just easier to point and yell, "Look, it's Superman!" and run the other way.
To loosely paraphrase a smart man (I oughta know who), the pubs MAY hang if they stick together, but if they don't, they will SURELY hang separately.
IOW, there is no guarantee of winning if they stick together, but losing is guaranteed if they don't.
Not a very comforting thought, knowing the senate pubs as we do.
