I grew up in SD, still have a lot of friends, family there. Have followed KN pretty closely. She has governed pretty well, but gets a little skittish when the big donor somewhat liberal companies threaten pulling money out if she doesn't toe the PC woke, more liberal line on DEI, ESG, etc.
But the thing that I'd think would sink her - though I abhor the dog story... like someone else here said, I like dogs more than a lot of people....
...is its a pretty well known and poorly hidden fact that she and Cory Lewandowski have had an affair for several years now, while she's still married with kids. I'd think that leaves more of a mark, than shooting an out-of-control, irredeemable dog.
