It does not matter how long she was considered top tier. She simply was. And now she is gone!!
Michele Bachmann was considered top-tier the day she won the Iowa straw-poll. Rick Perry entered the race the very next day and she was not top tier at any time afterward. Finishing with 5% in the Iowa caucus which is as close as she can get to home turf was the end of her road.
Like Ron Paul, Rick Santorum has never been considered top tier in this race, and yet he remains and has proven much stronger than supposed top tier candidates Bachmann, Perry, and Cain.
I will say this much for Santorum: as much as I find some of his views (particularly in regard to the right to privacy) and his statements (his comments about gay people) deplorable... of the remaining candidates, he is the one I find most likeable strictly from a personality standpoint.
I sometimes find Ron Paul very likeable too: he sometimes comes across as a genuine, caring, self-deprecating grandfatherly figure and when he is in that mode he is quite lovable. On the other hand he sometimes comes across as a bit of a fanatic and a guy whose motivation is planted in academic concepts rather than the real world, and when he gets into that mode it is a little off-putting.
Newt Gingrich I just find obnoxious and arrogant. He's clearly a very smart guy, and nobody knows it better than him. He seems compelled to take every opportunity to show off his knowledge and his preparedness, and to me it usually just comes off as a guy saying "hey everybody, look at me, I'm a big fat know-it-all!"
Romney leaves me cold. He's polished, he's slick... everything he says seems pre-meditated to come across as a crowd-pleaser. And while a lot of people probably do find that appealing, I have the opposite reaction... I don't find it genuine or sincere. We've all met people who when they talk we know they're saying stuff they think we'll like rather than stuff they actually feel, and to me Romney comes across that way. Of the four remaining candidates, he is the one who most comes across as a politician, and that's not really intended as a compliment.
Rick Santorum, on the other hand, I find just the opposite. I'm apparently one of the few women in Canada who finds Stephen Harper a likeable guy, but the reason I do is that in some ways he reminds me a lot of my dad. Rick Santorum is in the same vein: he reminds me of a regular guy. He has an authenticity and normalcy that the others lack. Of the four of them, Santorum is the only guy I could imagine as a co-worker or a neighbor. I could never vote for the guy, but of course I'm not their target voter anyway, and wouldn't be even if I were an American.
