Party Polarization and Campaign Finance

There is a lively debate today over whether or not campaign finance reforms have weakened the role of political parties in campaigns. This seems an odd argument in an era of historically high levels of party loyalty — on roll calls in Congress and voting in the electorate. Are parties too strong and unified or too weak and fragmented? Have they been marginalized in the financing of elections or is their role at least as strong as it has ever been? Does the party role in campaign finance (weak or strong) materially shape the capacity to govern?
