Republicans Fight in Gubernatorial Primary
Rick Scott, who like the billionaire Greene, bankrolled much of his own primary campaign with tens of millions of dollars, narrowly defeated Florida Attorney General Bill McCollum.
The race has veered both candidates to the right. Scott, who became a national figure when he organized a group that spent millions opposing the passage of Democrats' Health Reform Law, he unveiled an immigration proposal that would be even stricter than the controversial Arizona law that requires immigrants to carry proof of legal residency.
But Scott has struggled to distance himself from a massive $1.7 billion Medicare fraud fine -- the largest ever -- levied against the Columbia/ HCA health care company, when he was CEO.
Florida CFO Alex Sink, who easily won the Democratic primary, according to AP's projectoin, has stayed above the fray, but whomever she meets in November will be bloodied by the primary and ready for a fight.
Also in Arizona, former Vice President Dan Quayle's son is vying in a crowded, 10-person primary, for the Republican slot in a Scottsdale Congressional seat.
Ben Quayle gained some traction when he cut a political ad calling Obama the worst president in U.S. history, but he may have fallen in voters estimation when it became clear that he blogged for a racy website called thedirty.com under the pseudonymn Brock Landers, taken from the movie "Boogie Nights."
Quayle had initially denied the allegation. His father issued a last-minute email to supporters on the younger Quayle's behalf.
In Alaska, Sarah Palin looms large in the Senate race, even though she is not on the ballot. Palin endorsed the tea party-favored Joe Miller over Sen. Lisa Murkowski. Palin has a long history with Murkowski, whose father she defeated in the Republican gubernatorial primary in 2006.
Palin recorded a stinging last-minute robo-call against Lisa Murkowski, even though Murkowski has seemed to be a lock for the seat.
Palin's mystique as an endorser has fallen in recent weeks, having chosen the loser in the last six contested races where she endorsed a candidate.
