idea. vice president joe biden is calling close supporters and advisers this week, still considering jumping in the race for 2016. i consider him a friend. reporter: hillary clinton says she ll respect whatever decision biden makes. though her supporters have sent some signals to think twice. the problem is that joe biden is a very good guy and probably has no appeal whatsoever to people under 35. you think he s going to run? i can t tell. but i m worried if he does and doesn t do well, it will be hurtful to him and we all care about him deeply. reporter: donald trump is already treating him as an opponent. i think i d match up great. i m a job producer, i ve had a great record. i haven t been involved in plagiarism. reporter: a reference to biden s issues in law school, as well as during his 1988 campaign, accused of using someone else s line in a speech. here s jon stewart recently. the reason loose lips mcgee [ bleep ]ed up his 2008 president unrun is now the
coach, no advisor. he s his own apprentice, so to speak. what do you expect? i think he s down playing what he s going to he s managing expectations and i was speaking with kevin madden this morning who is a political mitt romney is one of mitt romney s advisors. he said in his estimation that s the first political presidential thing he s done, candidate thing he s done is he s managing expectations for the debate. but when he said if it doesn t go so well i ll ride off into the sunset. i said well, it sounds like you re tired, after this debate you ll bow out. he said no, he s energized. real quick. but even if donald trump doesn t do well, don t you think he ll say i m the greatest, i did great, i ve never been in debate before, i still mopped the floor with him ? i d say odds are yes in that direction for sure. interesting interview for sure.
