Why Obama's plans will hurt the nation

Economists reject his plans:

Barack Obama argues that his proposals to raise tax rates and halt international trade agreements would benefit the American economy. They would do nothing of the sort. Economic analysis and historical experience show that they would do the opposite. They would reduce economic growth and decrease the number of jobs in America. Moreover, with the credit crunch, the housing slump, and high energy prices weakening the U.S. economy, his proposals run a high risk of throwing the economy into a deep recession. It was exactly such misguided tax hikes and protectionism, enacted when the U.S. economy was weak in the early 1930s, that greatly increased the severity of the Great Depression.

(So why can't John McCain say this more plainly!!?????????)
