Joe Biden’s most famous supporter will make a campaign stop in Philly on Wednesday- former President Barack Obama.

While Obama has endorsed Biden, he has yet to make a public campaign appearance on behalf of his former vice president – mostly sticking to private fundraisers and a speech at the Democratic National Convention.

Obama is hitting the campaign trail this week while Biden remains in Delaware to focus on preparing for Thursday’s debate.

Are you surprised Obama hasn’t done more campaigning on Biden’s behalf? Is it appropriate for former Presidents to be involved in campaigns?
