Do you not find it interesting Spector figured out he is a loser 18 months before the election? I'd be interested in the actions of similar politicans; oh, say McCain ferrinstance.
McCain's only declared primary competition is Chris Simcox of the Minutemen.
There's a lot of dirt on Simcox. Restraining orders, domestic violence accusations, running a historically significant newspaper into the ground, embezzling money from MCDC, getting coerced easily by Washington interests (Deiner Consultants)... The list is quite long.
Simcox is an easy political kill.
I support closing the border and the PBA and all affiliated groups, but after Simcox's behavior for the last 3-4 years I have not been active with MCDC. If I can't see eye-to-eye with him, then it's unlikely that the less politically active portions of Arizona's population are going to like what they hear about him.
Now... if JD Hayworth jumps on after the easy Simcox kill... McCain is done. But I think Hayworth is holding out for Governor of AZ.
