News of poor conditions at a holding center in Arizona for undocumented, unaccompanied minors whipped Sarah Palin into a fury Friday -- so much so that she said she was on the verge of renouncing her ties to the Republican Party. She then accused President Barack Obama of orchestrating the "crisis" in Arizona in order to advance his own immigration reform agenda. "In this case, Obama’s refusal to enforce immigration laws and his blatant suggestion that his chosen illegal activity will be rewarded are proof of his tyrannical tactics," Palin wrote.
