Marky Kirk? I heard he allegedly had a girlfriend once, and of course the gay rumors but that’s ALL I’ve ever heard about his personal life.
However, I wasn't even referring to the gay rumors, there's all kinds of stuff out there about Kirk life that raises questions. There's allegations he attempted suicide as a teenager, and of course, he got caught in a huge scandal during his Senate race for embellishing his military record. I'm still trying to figure out why the heck he went to college in Mexico too (don't the DREAM act idiots always claim degrees from American Universities are sooooo much better than Latin American universities, therefore we cannot expect illegal aliens to go to college in their own damn countries?). He also served as an aide in a nursery school for a year (I did as well, and it's VERY RARE to have males in that capacity... the place I was at SHOULD be investigated because they didn't even ask me for a background check until I had been supervising children for two weeks!) and tried to pass it off as having a professional teaching career. Apparently none of the people who work at that nursery school remember seeing Kirk there, either. Then there's the story about him sending out political tweets at the Pentagon when he was SUPPOSED to be working, and that's an illegal violation of military rules.
Bottom line, I'd certainly say it's very likely his "personal life" is just as seedy as Sanford's, it's just that most of it hasn't been made public yet.
