Have you ever noticed how bread does not last long enough? You’ll buy a loaf, use four slices immediately, and then let it sit on the shelf for two weeks. By the time you try to use the remaining slices, its stale, or even worse, moldy. Well this loaf is a lot like Barack Obama’s political capital if it is not used quickly and correctly. In his first 100 days, President Obama could make delicious tuna and PB&J sandwiches. But recently it looks like he’ll let the bread mold grasping for bi-partisanship.

It’s clear that Obama’s economic stimulus plan doesn’t cut the mustard. By trying to get 80 votes in the Senate, he risks losing too much trying to appease Republicans. Obama doesn’t have to do this. The stimulus plan will pass easily with the 59 Democrats and a handful of moderate Republican Senators who support it.

But Obama is making good on the promise to be the President for everyone, not just liberals. While this is a laudable goal, Obama risks wasting his mandate even before his first term begins. When you have political capital, use it to make big advances on important issues, not to grab 15 unnecessary votes that will only weaken a desperately needed economic stimulus plan.

Obama’s popularity complex worries John Judas, too. He is concerned that “the president elect is underestimating the problem he and the country faces.” Judis calls for a much more extensive stimulus plan that includes funds to increase high speed public transportation. The closest equivalent we have to Europe’s impressive example is Amtrak’s Acela line, which is limited largely to the northeast corner of the country and is very expensive. But the extension of high speed transit would require a massive investment, which Congress has not even come close to supporting.

Judas continues:

Investing in high-speed rails would be very expensive, but unlike tax cuts–the benefits of which can be siphoned off in the purchase of imported goods–the money spent would go directly to reviving American industry and improving the country’s trade balance. That doesn’t just mean jobs creating dedicated tracks or new rail stations: Though the U.S. abandoned train manufacturing decades ago to the French, Germans, Canadians, and Japanese, this kind of production could be undertaken by our ailing auto companies or aircraft companies–if the federal and state governments were to place orders. And building trains that would run on electricity would be a paradigmatic example of the "green jobs" that Obama often touts.

In short, its worth the investment. Krugman agrees. $800 Billion is a lot of money, but if it funds an incomplete and insufficient plan, then it is wasted. I’d rather see a more expensive stimulus plan that serves as the final word and gets us back on track. We can kill two birds with one giant, expensive stone. Build a much-need U.S. high-speed transit system and stimulate the economy. This is possible without pandering to Senate Republicans.

Congressional Democrats are rightly frustrated by Obama’s concessions, and they are not afraid to show it. The stimulus issue was the final and most important disappointment in a week of Democratic division which included the Blago/Burris Illinois scandal, the Panetta/Fienstein miscommunication, and the choice of TV star Sanjay Gupta as Surgeon General.

Obama is the President of all Americans, red, blue, and purple. But he won a huge mandate in November’s election, supported by large majorities in the House and Senate. Obama needs to use that advantage to pass a working stimulus plan, even if it squeaks by with 61 votes.

Otherwise, he’s wasting perfectly good bread.
