McCain has a $6 million dollar war chest and an equal amount readily available and unlimited fundraising capabilities. Hayworth is looking for lunch money.
Governor Palin may be useful in tamping down any insurgency but McCain would be better off with a Romney endorsement. Lunch with Romney would solidify the eastern suburbs of Phoenix and the counties east to New Mexico. Those are the districts with heavy LDS influence. McCain would win without either Palin or Romney but the results this time will be compared to his previous wide margins. He doesn't want to go into his last term limping like Goldwater with a 5000 vote win.
If he'd declare Hayworth wouldn't be looking for lunch money. He'd be getting Scott Brown level money from in and out-of-state. Others in Arizona have a very different take than yours.
And you sure do make a hopeless case for someone who likes Hayworth and dislikes McCain?
you say, “not Senate material”. Will you please clarify?
