Just pointing out that in my early 2017 analysis, IN-05 was one of 47 "prime" districts for pickup opportunities. IMO, IN-2 & IN-9 should also get some attention (though high turnout elections make it difficult to win in them).
With that being said, maybe with somebody like the Booty Judge at the top of the ticket it'd be worth it...but it's realistically a steep climb. I'm not sure as to the caliber of the Democratic candidate in 2018, but from a cursory glance, I'm guessing the performance was more of a baseline than an overperformance.
