David Broder’s column tomorrow discusses Citizens United and campaign finance reform.

On Tuesday, the Senate Judiciary Committee will convene to canvass ideas for going further in order to limit the newly proclaimed rights of domestic corporations and unions to finance campaign ads from their own treasuries.

One option, a Schumer aide told me, might be an attempt to preserve the ban for corporations that employ Washington lobbyists; or enjoy government contracts; or receive government bailouts or other substantial subsidies. Another idea is to require the chief executive of a company to appear at the end of its political ad, just as candidates already have to do.
