That they will do what they can for that incumbent....most important, party unity is at stake here!

It would look like a stab in the back if the president didn't support the incumbents in his own party to the other incumbents in that party....even if that same incumbent in question has stabbed you in the back in the past....

The president must be bigger than that, a uniter and let the chips fall where they may....No matter how he personally feels.

Hopefully they'll come out the way a president really wants them to.
