Krugman is an inveterate liar and the Times has become a cesspool of the worst bias in liberal media.
Krugman’s problem is that he is a very smart Keynesian who believes in a lot of socialist rot, and to make his ‘case’ he is not above lying, misusing statistics, and creating strawman arguments (a favorite of Obama btw, who is so much for strawman arguments he literally decalred the ‘real Romney’ wasnt at the debate; um,nope, the real one was there, the guy who WASNT there was the strawman Romney that Obama has been running against.)
You could get lost in a thicket fighting every false premise, cherry-picked data point and bogus argument of Krugmans. Best you can do is point to some critiques of Krugman:

An open mind might realize that Krugman is blowing smoke, as he often does. He is just cheerleading for Obama’s phony strawman arguments, and defending Obama on a basis of hope not reality. A closed mind ... well, why bother with a closed mind.
You can pass this along and see what he/she says. Latest blog post critiques Krugman’s latest.
