Trump won Kentucky by 31 points while Paul won by 15. Paul underperformed significantly in every corner of the state except Northern Kentucky, where he outran Trump's margin by about 5 points in each of the three Cincinnati suburban counties. In most rural areas he was 20+ points behind Trump. In the Louisville area he was 5 points behind, and in Lexington 10 points behind. The difference in results strikes me as very odd. I don't think it's an error, as all three counties have this pattern. I've never seen something like TV ads make such a big difference in a general election before if it was the case that Paul was unanswered in the Cincinnati market. Paul also resides in Bowling Green, Kentucky and not in Northern Kentucky.
The GOP Brand hadn't been fully Trumpified yet, and he was never a particularly good fit for the state.
