One gets the impression that most of the posters in this thread didn't actually read/consider the article, but are merely regurgitating talking points... sigh.
As to the article I'm largely in agreement, and felt the same way in 2009. It was a massive selfnuking by the administration to not pass their tax cuts separately and first.
I think this was a more insightful part of Trende's piece, not the part on the potential second stimulus. The stimulus as passed was perceived by the public as a jobs bill for "shovel-ready" projects. That was only a small part of the actual bill so it isn't surprising that many of the public were underwhelmed by the jobs created given the magnitude of the spending. Here's the breakdown chart from wikipedia.
The bill was not going to garner much GOP support, and the tax cut and infrastructure pieces weren't going to have as much opposition as the health and education spending components. A split could have been very helpful in framing the debate with tax cuts and infrastructure right out of the box. Education support and job training as well as housing support could have happened after Franken was seated. The healthcare and Medicaid components could have been made part of the later healthcare bill. If the state Medicaid relief was also part of that healthcare bill it would have put many of the GOP opposition states in a box on the overall healthcare bill.
