been following this, we've said watch cruz in iowa, watch cruze in iowa. this race is sort of dividing into three distinct lanes. trup p has this pop lust wing of the party that had never participated in republican parties before. he's excited about this. you have the third of the electora electorate. then you're going have marco rubio appearing as sort of the more traditional business wing of the party, more traditional republicans. think of the old eisenhower republican, bush republican. and if we're looking at three, a third, a third, a third, depending on the state, that's pretty much where we're headed, boy, this could make for a fascinating next six months and could mean we're actually covering a news story in cleveland for the convention. >> i go back to howard dean. everybody thought he was the
