the guy. >> right. the key to romney's success will be the electability question. since we just saw rick santorum, 7% electability. this is a man who lost his last senate race as erik erikson pointed out. there are clearly questions about that. same for newt gingrich. and, of course, for ron paul and perry. so, again, this is romney's ticket if, when people go to the caucuses, they actually think about electability or somebody they like. we just don't know until we see that entrance poll on tuesday. >> all right. well, thank you, gloria. we shall see, wolf. but, obviously, this picture shows it right here. it really all coming down to electability for romney. >> gives us a good snapshot of what's going on in iowa right now, guys, thank you. we're watching the last big push in iowa before the caucuses tuesday night. we'll have an update on the last-minute pitches, the last-minute attacks as well. and iowa is just one small step toward getting the delegates needed to win the republican presidential nomination. what does it take to reach the magic numbers? stay with us.
