McCain May Re-Suspend Campaign

Link. My big question is why? Can't the guy have a campaign going on while also doing his job as senator?

Let's say he wanted to go back to Congress and twist a few arms. Then just do it. The campaign doesn't need to be suspended. If he wants to take a few days off and do something, he could just do it.

When they take a vacation the campaign is still going on. There's no difference.

Suspending a campaign is just a stunt.
