Deval Patrick has made many mistakes in his bare two months as governor. None of them particularly serious, although two or three reflect a strange strain for luxury in his character. OK, he wants his own privately paid-for summer vacation McMansion, let him go right ahead. But an article by Frank Phillips in Tuesday's Globe revealed that the governor had made a phone call to Robert E. Rubin, former secretary of the treasury and now a top official at Citigroup, to smooth the paths for a corporate loan. So who was the lender? ACC Capital Holdings, the owner of Ameriquest. This firm is well-known for predatory lending, and it was an issue in the campaign because Patrick had been on the board of ACC. Very sloppy. Very dirty. And oh-so-stupid. Stupider still was Patrick after he has apologized. He said he did not call Rubin as the governor of Massachusetts but simply as a private person vouching for the company. And, of course, Rubin pushed from his mind the fact that Patrick was, indeed, governor. Patrick was paid $360,000 a year during the two years he served as an ACC director. And now ACC has gotten its money's worth. Citigroup has put a large cash infusion into the troubled company. By the way, Citigroup also does much bond business with the state. Did that ever occur to Patrick when he called Rubin?
