Scott Brown-R is more likely to run for Governor than Senator.

6. Don't forget, governorships are better for national careers then senators

If I were Brown I'd be thinking long term, I'm more likely to get a better job after I'm out of office if I serve 1 or 2 terms as governor then another term as senator only to lose again later.

And who knows, if he kept his popularity up in such a situation he could start to look like a logical VP pick to a republican nominee in the future.

There's just not the same long term career opportunities going back to the senate once he loses again in a future (probably presidential) year, other then being a lobbyist.
