Rumor has it that New Gingrich is still a presidential candidate — I know, I kind of forgot about him, too — and he’s still offering unique words of wisdom.

Newt Gingrich took to FOX News Monday night to compare President Obama to, of all people, Paul Krugman, one of the White House’s fiercest critics.

“This is a Paul Krugman presidency,” Gingrich told Bill O’Reilly. “[Obama] believes that stuff. He actually believes in left-wing economic ideas. The only problem with them is that they don’t work.”

Two things. First, “left-wing economic ideas” — which would apparently include measures like job-creating public investments and aid to states — are the most effective policy options available. Newt doesn’t know what he’s talking about.

Second, does Newt Gingrich ever actually read Paul Krugman? I don’t know the Nobel laureate personally, but reading his columns, blog, and Twitter feed, and watching his media appearances, I’m left with the impression that Krugman loathes President Obama. He made little effort to hide his aversion to Obama as a candidate in 2007 and 2008, and has been quite candid in the years since about his near-constant frustrations with this White House. At times, I get the sense that Krugman’s take on this presidency borders on contempt.

“This is a Paul Krugman presidency”? I suspect that would probably be startling news to Paul Krugman.
