Do principles or issues play actually any role, or do you just vote for her because she "has success"?
She is a republican who has the cojones to not march in lock step with the party and has won every election doing just that.
One can also call it opportunism.
And one can also call it having the courage of her convictions. Perry is for whatever will get him elected. I do agree with her re:immigration. And John Cornyn. And W. And W got elected Gov twice endorsing a path to citizenship.
You do not have to agree with me. You are free to vote for whomever you want. It does not bother me. Nor does it upset me for some to disagree with me. I have been married to a democrat for 43 years and I havent killed him yet.
