Palin razzes daughter for saying she's decided on 2012

Some political observers took her visit to Iowa, the first in the nation caucus state, to mean that she is again thinking about running. But the ex-governor hasn't given any specific indication to that effect.

Bristol Palin, meanwhile, told Fox that her mother "definitely knows" whether she'll run and said she would like her to enter the race. 

"We've talked about it before, but some things just need to stay in the family," she said.

Should she run, Palin said that she would be committed to the Iowa caucus process, even though she has yet to make any formal inroads in the state.

"110 percent," said Palin when asked if she would commit to Iowa. "Doing as much as I can to garner that support. It's necessary."
