Incredibly Dumb Thing Said

EJ Dionne writes in the Washington Post:

"Wall Street conservatives — well-represented on the financial cable shows and the Wall Street Journal's editorial page — are arguing that the stock market is collapsing because Obama wants to institute a relatively modest set of tax increases on the wealthy, starting in 2011.

"But these voices supported lower taxes on the rich when the economy was bad, when the economy was good and when the economy was so-so. They have no credibility."

Well, golly, so Dionne finds that conservatives consistently favor lower taxes and then extrapolates that this somehow damages their credibility. That is a gobsmackingly dumb conclusion to draw.
