If I were advising the Republicans I would've told them to vote against the stimulus package. I would tell them to make the point clearly that if they were in charge, the bill would be a different bill. They're a competing political party and they need to, you know, highlight the fact that their vision for America is actually different. I appreciate that members of both parties don't always toe the line completely, but on a bill as big as this it makes perfect sense for it to play out as it did.
Of course the flip side is that Dems should've pushed the best plan that could pass the Senate instead of pushing some pointless fantasy about bipartisanship.
