Rep. Lois Frankel was surprised this week when she received a text with a picture from a campaign mailer promoting Democrat Scott Wallace that showed her picture among 75 other members of Congress.

“The Congressional Progressive Caucus Endorses Scott Wallace,” read the text above the picture. The only problem was Frankel had endorsed Wallace’s opponent in Pennsylvania’s 1st District — Navy veteran and attorney Rachel Reddick.

Frankel also learned that another Pennsylvania Democratic candidate, pastor Greg Edwards, had listed her as backing his campaign in a Facebook post touting the Progressive Caucus endorsement. Frankel is actually supporting one of Edward’s opponents — Allentown City Solicitor Susan Wild.

The mixup is an unexpected symptom of crowded Democratic primaries: that members of congressional caucuses might not agree with the group’s endorsed candidate.

Frankel reached out to CPC chairman Mark Pocan, D-Wis., about the issue, and said the caucus should have a discussion on how to proceed. Frankel attributed the issue to “some intense primaries.”
