She's is primarying a four term Democratic congressman among other things. How dumb can you get thinking you're going to be this massive difference maker by replacing one veteran lawmaker with a freshman legislator ON THE SAME SIDE OF THE AISLE.
If she wins, she'd actually be weakening the Dems in the general election and if she wins the general she'd weaken their caucus in the house simply because she'd be a frosh legislator and not a four term incumbent. If I was advising the guy she's running against I'd hammer this point over and over in the runup. You want to defeat Trump's agenda? You vote for me, the guy that actually has won the district against the GOP challenger four times in a row.
FWIW, I did work in electoral politics (including advising campaigns) before getting burnt out on the stupid. Sorry for the powerlevel.
edit: ah christ, the district went 97% percent Dem the last time through. It's as safe a seat as it gets for them. In a way that just makes it even more pathetic. Go try and win a seat no other Dem has if you think you're such hot shit.
