Adam, random ads do not have the impact you think they do. Kasich is leading and will be re-elected because he is decently popular and has maintained a comfortable approval rating, and Fitzgerald is a nobody. I'm sorry, but it's not that complicated.
Dude, people watch television. The average Ohioan doesn't follow state politics much, either, and all you have to do is tune into any kind of news station to see all of these ads airing everywhere which give these undecided Ohioans who aren't interested in politics at all an edge towards Kasich because of how brightly envisioned he is as this comeback leader. PPP had his approvals in the 40s so it's not because Kasich is popular because he really isn't. His approvals are relatively considered high, but his favorable's are below average and he's still polling only in single digits of a Democrat who 7 in 10 Ohioans don't know enough about even though Ohio historically has Governor elections that end in a wide margin disparity. FitzGerald still has time on his hands though to define himself before Matt Borges, John Kasich or Chris Christie can define him themselves and he at least has some money to do it with.
You realize Kasich will have an advertising campaign against FitzGerald as well, yes?
