The GOP establishment is circling the wagons for McCain for a variety of reasons.
Some actually support him.
Others see McCain’s impending defeat as a threat to them.
If McCain can be removed at the ballot box, then so can they.
If McCain can be removed at the ballot box, then NO incumbent is safe.
If the GOP establishment can not co-opt the Tea Partiers, they will turn against them.
As for the Democrat Party, their motives are already abundantly clear.
