Near Chicago here, so we get Chicago stations. No effect on Indiana or Illinois, but close to Wisconsin, and they get the same stations and games.
At least the Harris ads won't be on much longer. I don't watch any sports. I'm an old lady, but understand your frustration. I subscribe to several YouTube channels, mostly historical, and they either start with ads for stupid crap, or lately, political ads featuring Bernie Sanders, Harris, and Obama. I make sure I mute my laptop, and hit the "skip ad" button when it shows up.
