Romney has made much of his experience at Bain, and as such it IS fait game. But the bashing of Bain, using using words such as "vampire" (ripping off Newt Gingrich, who accused him of being a vulture), and attacking the work of Bain as somehow "unfair", is NOT fair.
Also, you may want to consider than current polling suggests that more than twice as many people see Romney's Bain experience as a positive, as do those who see it as a negative. Don't get me wrong, no profession is made up of saints, especially venture cap folks, but most people are smart enough to know that they aren't all bad either, including the cities and states that rely on their investment dollars and the public employee unions that rely on their profits to make pension payments.
As to the notion that being a CEO and being POTUS are "totally unlike" each other, you may want to walk that back a bit, or even a lot. Executive leadership, in any setting, is highly related, It's one reason why governors running for the presidency typically fare better than former congressman. The whole "buck stops here thing", you know?
