what's the other definition of best and strong if it's not electability? >> well, i think it's not just electability. it's their record and their stand on the issues. i think people respect what governor perry has done as governor of texas, in creating jobs. they look at newt gingrich as an idea person. they see rick santorum as having solid conservative record. they see ron paul as somebody who is consistently voted against increasing the federal debt, manipulating the currency. so they see some strengths in all of these candidates, but, in the end, they have to choose the one they think is best and they think will be the best president for our country. so it's an important responsibility. iowans take it seriously. i'm expecting we're going to see a great turnout at the republican precinct caucuses tomorrow night. >> what do you make of the surgery rick santorum? no one in the race has spent less money and arguably until he went up in the polls, nobody got less attention.
