Yes that rumor was reported of Heidi and Carly catfight in a rest room. Could just be that Heidi interpreted (correctly) the body language (like Cruz's lecherous full-frontal hugs of Carly, not to mention the weird hand-holding thing.) Usually in situations like that---Hil was this way with Bill---the power-hungry wife accepts the hound dog catting around---but takes umbrance when it's in her face and in everyone's face while the faithful wife is fulfilling her own part of the bargain.
That was one weird full frontal lower body grabbing hug when he announced Carly, that is for sure. She almost lifted her legs around him. And people on the live thread were saying “it looks like she is in love with him.” So when the rumor came around about the cat fight in the pizzeria bathroom, it seemed plausible.
Thank goodness they didn’t win. I don’t think we’ve ever had a president having an affair with his veep before. However, if Reagan had been interested...
