Mitt Romney goes incognito at Costco

The celeb stalkers of TMZ spotted Mitt Romney at a Costco in La Jolla, Calif., this week.  It looks like the Romneys were doing a bit of Christmas shopping:

TMZ noted that Romney purchased some toy cars that are -- gasp! -- manufactured in China!  "Of course, Mitt railed against China during his bid for the presidency ... claiming the country is manipulating currency and stealing American manufacturing jobs," the site railed.  And then the hard truth set in:   "We tried to find some American-made toy cars that Mitt could've bought instead ... but we couldn't ... not even Hot Wheels ... they're manufactured in China and Mexico."
