Her record doesn’t support your allegation:

I take it back, she seems solid on the issue that matters most.
Here ya go:
“A compassionate solution for the illegal immigrant population living and working in the United States can be accomplished without resorting to amnesty. Current illegal immigrants should not receive all the rights and privileges they would have been eligible for had they come legally. They should not be eligible for citizenship. To pardon lawbreakers and reward them with the objective of their crime is inappropriate and will accelerate the flow of illegal immigrants.”

This is the classic RINO no-amnesty amnesty: they get to stay here legally ever after, but because (at least at this stage) they don’t advocate regular American citizenship for them, they try to claim that they are not supporting amnesty.
