The best explanation for why Romney may run again: He's bored

It’s hard to imagine why anyone would want to put themselves through the grueling presidential campaign process a third time and risk national embarrassment if they fail yet again, especially if they are worth hundreds of millions of dollars and could spend their time on permanent vacation if they so desired. But Romney doesn’t sound like the type of guy who would enjoy spending his days reading the Economist by the beach. It sounds like he wants to be where the action is — and nothing would provide more action than being president of the United States. So with what is likely his final opportunity to achieve the golden ticket approaching, the former Massachusetts governor seems to be gearing up to go all-in.
