In his Monday column, Krugman explores Romney's claim, in the video, that the economy will perk up just from his election, without having to do anything at all.
In fairness to Mr. Romney, his assertion that electing him would spontaneously spark an economic boom is consistent with his party’s current economic dogma. Republican leaders have long insisted that the main thing holding the economy back is the “uncertainty” created by President Obama’s statements — roughly speaking, that businesspeople aren’t investing because Mr. Obama has hurt their feelings. If you believe that, it makes sense to argue that changing presidents would, all by itself, cause an economic revival.
There is, however, no evidence supporting this dogma.
