This month marks the fifth anniversary of the Citizens United decision, which struck down limits on corporate campaign contributions. Our guests: Sen. Jamie Raskin, a Democrat from Montgomery County who wants to require that shareholders have a say in corporate contributions; Ilya Shapiro, senior fellow of constitutional studies at the Cato Institute, who argues that Citizens United is widely misunderstood; Charlie Cooper, president of Get Money Out-Maryland, on the group’s effort to get a constitutional amendment against "corporate personhood.”
