Sometimes, Boston's cab drivers are telling the truth; the credit card machines don't work - and it's not their fault.
According to (Boston's own) Charles Pierce of Esquire, the Romney for President campaign shut off staffers' credit cards  in the middle of the night on Tuesday, leaving the Boston crew scrambling for money.
From the moment Mitt Romney stepped off stage Tuesday night, having just delivered a brief concession speech he wrote only that evening, the massive infrastructure surrounding his campaign quickly began to disassemble itself. Aides taking cabs home late that night got rude awakenings when they found the credit cards linked to the campaign no longer worked.
Oh, well, need to save that money for 2016, right?
