My guess is that the GOP governors saying they won't take stimulus money is just more posturing. But the really lame part of it is that they want to pick and choose getting federal money without the strings attached. Sorry, that isn't how it works. Just like how highway funding is tied to drinking ages, you don't get fed bucks for free.
And if they really do refuse? Well, as the rest of the states recover, the states with these cornpone governors will probably make some stimulative decisions at the ballot box.
