The Buckeye state has been considered a bellwether since at least 1840, when newsman first uttered “As Ohio Goes, So Goes the Union” about that year’s presidential contest. Many years later it remains a battleground, and a reflection of a changing America with all its contradictions—the good, the bad, and the ugly.

It’s becoming older and whiter than most of the country.

Ohio’s population is 79.8% white (compared with 61.6% nationwide), and the country’s seventh-most-populous state has resisted the demographic trends of immigration that are turning many states blue.

Some of those demographic shifts could harm the state’s economic outlook. An older population, a low birth rate and much outmigration could constrain Ohio’s long-term prospects, Moody’s says.

The hard-hit state recovered from the recession—and 11% unemployment—quickly, thanks in part to trading partner Detroit’s auto bailout. And, like a few other U.S. success stories, shale deposits in the state’s northeast helped too.

Big business loves it (mostly).

Once a manufacturing mecca, Ohio is still home to 24 Fortune 500 companies, including Procter & Gamble pg and Kroger kr in Cincinnati.

However, after giving Ohio a hard look, GE ge CEO and Cincinnati native Jeff Immelt passed on his hometown and moved his company’s headquarters to Boston.

The export hub is not loving trade.

Ohio is the nation’s eighth largest exporter, shipping $50.7 billion, and roughly 47%, of its manufactured goods abroad in 2015. Still, the state is a stronghold of antitrade fervor, which was on display at Cleveland’s 2016 GOP convention.
