>> rose: welcome to our program, tonight we continue our look at president obama and his presidency with john harris, editor-in-chief of politico. >> his great success in 2008 was he transcended the internal divide in the democratic party. these questions that most democratic presidents, presidential candidates get. hey, are you a new democrat, a so-called d.l.c. democrat, or are you more traditional old-line liberal? he said those questions are irrelevant. i'm barack obama. he united the party around his personal story and, of course, around the democratic party's disdain for president bush and that was enough. he never defined himself in a philosophical or ideological way. that was great in the campaign. i think it doesn't work as effect ily in governance.
