( CNN ) Vice President Joe Biden opened the door Wednesday to a potential presidential primary challenge to former secretary of State Hillary Clinton in the Democratic primary . `` Yes , there is a chance '' he would challenge Clinton for the Democratic nomination in 2016 , he said on ABC 's `` Good Morning America . '' `` But I have n't made my mind up about that . We 've got a lot of work to do between now and then . There 's plenty of time . '' Both Clinton and Biden have made no secret of their interest in running in 2016 , but Clinton allies have been building an organization that encompasses many of the key strategists and operatives in the Democratic field , and she holds a significant double-digit lead in every poll of the potential field . Biden does n't always come in second — that position in Democrats ' hearts is often held by Massachusetts Sen. Elizabeth Warren , a liberal icon whom many progressives see as their only alternative to Clinton . But Biden said he feels there 's a chance for any candidate to break ahead . `` I think this is wide open on both sides , '' he said of the presidential primaries . `` Right now my focus is getting implemented what the president talked about last night : to nail down this recovery and get the middle class back in the game . During a round of interviews following Tuesday night 's State of the Union , Biden continued to talk up his chances , saying on NBC 's `` Today '' he feels he 'd `` do a good job '' as president . Although by this time in 2007 , Biden had already declared , he said Thursday he does n't need to decide until the summer about another White House run . In the meantime , the vice president has friendly remarks for Clinton — he called her a `` really competent , capable person and a friend . ''
