Barack Obama held a rally-concert today in Columbus, Ohio. 15,000 supporters turned out to see Springsteen, Jay-Z and Barack Obama at the Nationwide Arena in Columbus.
The Obama-Springsteen concert in Cleveland back in 2008 drew 80,000 people.
That means they lost 65,000 supporters between 2008 and 2012.
