No, she's just the one doing the reporting...
The original quotes came from a 1984 Cincinnati Enquirer article. The Enquirer endorsed Schmidt in 2005, so I don't think they're involved in a conspiracy against her. The Hill is a high quality newspaper that gives a ton of information about Capitol Hill politics. If anyone thinks the Hill is biased against them, they need to remove their tin foil hats.
As for the author, even if this was Dennis' daughter and she was as bad as he was, I'm not sure she'd spend her time to help a candidate who's as conservative as Steve Chabot. If Jackie wanted to fill Congress with liberals, she wouldn't be helping someone as conservative as Bob McEwen. There's plenty of Republican incumbents vulnerable to Democratic challengers. And this conveniently ignores the fact that reporters have editors who assign and review stories before publication.
