It's unusual for national money to pour into Alaska for midterm elections except for an incumbent. But Palin changed that game.
Palin's quiet emergence in the Senate race was a testament to the long-standing feud between the two families. Palin was one of a handful of candidates Murkowski's father, Frank, had picked to replace him in the U.S. Senate when he became governor in 2002. In the end, however, he ended up choosing his daughter, Lisa, despite allegations of nepotism.
Palin beat Frank Murkowski in the 2006 gubernatorial race as his ratings tanked.
The cold relationship between Murkowski and Palin is widely documented. Murkowski took a stab at Palin for stepping down as governor, and assailed the former veep candidate for being out "for her own self-interest" and not "Alaska's interest."
Palin, meanwhile, targeted the family dynasty in her robocall for Miller.
