These debates "ain't gonna matter".
When Bevin lies as much as he does, it matters.
Do you think Kentuckians care about that? After all, Kentucky gave 63% of the vote to Donald Trump, who is a notorious liar. Many Kentucky voters are more concerned about the "caravan" and "keeping out Muslim extremists", than they are about economic issues, at least in the context of this election.
At the state and local level, Kentucky is more Democratic than many Trump states. There are still many Trump counties that have voted Republican in Federal elections that still have Democratic local officeholders, and these officeholders will support a Democratic candidate for Governor.
The Democratic "turnoff" for Kentuckians will be, somewhat. the far-left focus of the national party's candidates, and the fact that we've got them on display so prominently this early doesn't help. The impeachment issue doesn't help here, either. But Bevin has his liabilities, and he's a guy that ordinary Kentuckians might not vote for, simply because they don't like him, and because they self-identify (still) as Democrats, even though they have been far from the national party for years now.
This much is true. Many of Kentucky's counties still have a majority of their voters registered as Democrats (even though most of those Democrats do not vote as such at the federal level anymore). But these numbers too, are beginning to ebb, which is another sign of the partisan realignment that is taking place. And it is true that Kentucky still has remnants of its Democratic heritage present, with the Attorney General (Beshear) and Secretary of State (Lundergan-Grimes) still in office. But those too will soon be gone.
Grimes is NOT running for re-election, so the SOS seat is obviously open. I expect the GOP to pick up both offices next Tuesday.
