President Trump won Kentucky by almost 30 points, but a competitive House race has emerged in the state's 6th Congressional District. Rep. Andy Barr (R) has represented the Louisville-based district, where he's received at least 60% of the vote in his last two elections, since 2012. But Democratic nominee Amy McGrath, a retired Marine fighter pilot, is giving Barr a run for his money. Democrats are focusing on health care in the race, while Republicans are trying to paint McGrath as a liberal who's out of touch with Kentucky. This is one of the most heavily watched races on both sides.
