>> so much of vice president biden's campaign is not about candidate performance. the nation knows him. democratic voters in many respects are comfortable with him. when i was at a majority-black church in south carolina a few months ago, voters told me they like vice president biden, they respect him from his tenure with president obama. and so that name i.d., that whole persona has propelled him forward in this democratic race. and it will likely continue to keep him in this race, at least until super tuesday according to most democratic strategists, but they say he is someone who is moderate and he's crowding out mayor buttigieg and senator klobuchar for the moment. he's still winning over working class support. >> robert contra costa on the grounds of the u.s. capitol, thank you very much for being
