Former President Clinton endorsed Rep. Mark Critz (D-Pa.) over Rep. Jason Altmire (D-Pa.) Thursday, a huge boost for Critz ahead of the April 24 primary.
PoliticsPA.com first reported the story.
Clinton joins nearly every major union in throwing its support behind Critz, who started the race as a major underdog because much of the new district is Altmire's old territory. Critz immediately released a new ad featuring the Clinton endorsement and slamming Altmire for distorting his voting record.
