I wrote once, Krugman likes Rubin. Here's more by Paul himself.
"...it's pretty clear what John Kerry's economic philosophy will be. He's surrounding himself with advisers closely tied to Bill Clinton, and even more closely tied to Robert Rubin, the legendary former Treasury secretary. In office, we can surmise, Mr. Kerry would follow a Rubinesque strategy of bringing long-term budget deficits under control through a mixture of tax increases for upper-income families and spending restraint. No doubt he would move slowly on deficit reduction as long as the economy remained weak, but his advisers would tell him, as Mr. Rubin told Mr. Clinton, that responsible long-run budget policies are good in the short run, too, because they help keep interest rates low...".
And, he really hates Mankiw: "...George Bush has, of course, tried to be the anti-Clinton in all things. His advisers rejected Rubinomics and hearkened back to Reaganomics, insisting that long-run tax cuts, never mind the effect on the budget deficit, are the key to growth. For three years, they've had nothing but red ink to show for their efforts. Now they've had one good but not great month...."
