It’s hard to conclude that he isn’t when you find evidence that he tailors his opinions to say whatever helps Democrats and their statist agenda.

Don Boudreaux exposes Krugman in this letter:

To the Editor:

Noting that “it’s important to have some perspective,” Paul Krugman
argues that while Uncle Sam’s budget deficit is now large, “we also
have a huge economy, which means that things aren’t as scary as you
might think” (“Till Debt Does Its Part,” August 28). Whew! No cause
for much concern, for the size of America’s GDP swamps the size of the
budget deficit.

During the Bush years, however, Mr. Krugman preached a different
gospel. For example, in his February 11, 2005 column – devoted to
condemning tax cuts – he insisted that “the deficit is indeed a major
problem.”

So let’s take Mr. Krugman’s advice and get some perspective. In 2005,
when Mr. Krugman insisted that government’s budget deficit was “indeed
a major problem,” that deficit was 2.5 percent of GDP. Today, when Mr.
Krugman no longer is very concerned about the budget deficit, that
deficit will be about 11 percent of GDP.

Sincerely,
