A lone GOP contender takes a hard line on gerrymandering

Speaking with the Columbus Dispatch, Kasich called for redistricting reform (which, we'll note, has come up before this cycle). "I support redistricting reform dramatically," he said according to the paper. "We carve these safe districts, and then when you’re in a safe district, you have to watch your extremes, and you keep moving to the extremes."

In other words, creating a House seat that's safe for Republicans means the primary becomes about who can be most appealing to primary-voting Republicans, which can benefit more extreme candidates. The same thing can happen on the Democratic side, too, but 12 of the state's 16 seats are held by the GOP.
