I cannot vote for McCain because he IS one of the main authors of the CIR-Amnesty bill. He has also insulted people with name calling those who wish to keep US sovereignty and enforce our existing laws.
I just could not cast a vote for such a person. I see nothing in McCain that shows he could be trusted to look after US citizens first.
Anyone running for POTUS should be required to reveal their medical files, including treatment for psychiatric problems.
