States that supported President Donald Trump in the 2016 election are doing better economically these days than those that went for his opponent.

Five of the seven fastest-growing states in the U.S. during 2019 went red in the last presidential contest, according to a trend tracked by Yelp that could come into play as a bevy of Democratic hopefuls look to unseat the Republican incumbent in a race that will heat up soon.

An index that the online review site uses to track growth showed that the gap that Republican-leaning presidential states enjoy over Democratic states widened to 2.8 points from 1.3 points in 2018.

Of the seven best-growing states — North Dakota, South Dakota, Wyoming, Louisiana, Alaska, Hawaii and Maine — only the latter two voted for Hillary Clinton in 2016. Moreover, the seven slowest-growing states and districts by Yelp's measure — Oregon, California, Illinois, Massachusetts, New Jersey, Connecticut and Delaware — all voted Democrat.
