Reagan was 69 when elected so at 71 McCain isn't too old.
Romney seems like he would make a great CEO of America but I am not sure how he will line up socially. Being a Mormon does not bother or scare me and if anything he may favor the evangelical social platform better than any other president ever considering that by and large Mormons are ethical and moral people who believe in family and such. The polygamists are not the norm.
Rudy is not conservative and if you take away Sept. 11, wish we could, he wouldn't even be in the race. Or if Sept. 11 would not have happened in New York he wouldn't be in. He is kinda using that to propel himself and to me, to me people, it's sorta unethical.
I was for McCain in 2000 till the GOP nominated Bush then I voted 3rd party, Buchanan. McCain is a maverick as they said and had he won in 2000 I believe the wars in both Afghanistan and Iraq would be over and WON and OBL's head would be on display all over the WWW or he would be in millions of small pieces somewhere in a desert.
I do not like McCain/Kennedy and john's immigration record scares the heck out of me. Maybe, just maybe, he is gotten the message. Who knows, he may pick his good friend Thompson as his running mate. I could certainly throw my support behind that duo.
