I don't have a problem with Republicans who, on balance, wanted the bill to pass but still voted against it. I don't really think it's "cowardice" or whatever, they're simply making it clear that they're the opposition party. And that's a good thing! It's only in bizarro Broderville, combined with the annoying supermajority bits of the Senate, that anyone really thinks differently.
...to be clear, I don't think the opposition party should always oppose everything. But this was a lot of money. A Republican bill would have been very different! There's nothing wrong with making that point.
