What a perfect issue for the Republicans to hype for their agenda.
They would like to defend BP, based on their 'corporations can do almost anything and get their backing' position, but that's politically costly.
And they love to attack unions, who cost the rich money by making pay higher than substinence and not having an oligarchy of wealth.
This lets them do both - by hyping the story, they can change the subject from BP's wrongdoing, and attack unions and the Obama administration, and even praise Bush.
Of course the story will get into their talking points, it serves their agenda very well.
I wouldn't look to them for any responsible issues to get answered like the actual impact of the law on this situation. No, the oil would already be gone but for Obama and unions!
The Republicans have been far too willing to screw workers with anti-union policies - for example, the Bush adminstration creating massive federal programs with non-union work.
That was an abuse of such 'exemptions' for their pro-rich agenda.
It seems it would be justified to have an exception here, if it would help. That's a question to look into. But not to have the issue hyped without any answer.
