Why would Hillary not be investing here if it were this close? I'm skeptical.
Cause it doesn't matter. Too small.
Then why would she invest in NE-02?
Cause her campaign is quite inept.
No, it's because she is going after every electoral vote she can plausibly get, just like she went after delegates in the primary. If you have the resources, one would have to be pretty stupid not to do this. And ads for NE-02 bleed into parts of Iowa as well, so it's a double investment. Given the current dynamics of this race, it is smart, not inept.
