Your scenario makes sense. Obama goes to on election eve and then claims his gravitas is what saved Chris Coons from certain defeat at the hands of those “right wing extremist tea-baggers”.

It’s really all they have left. And even that might not work.

Three times a charm if Obama loses again. :-) Obama showed up in NJ multiple times to support Corzine to take on Christie where Obama lost.

Can Obama rescue Corzine in New Jersey governor's race?

And Obama went to Massachusetts to support Coakley for Senate against Brown where he lost again.

Obama's "gravitas" may get to zero if Coons wins. ;-)

Only reason that doesn’t make sense, though, is that they’d be playing up how close it is now if that was the plan. If they’re saying she’s down by 10 and it turns out that she loses by less than that, they can’t claim that Obama saved anything.
