President Obama, Hillary Clinton Will Campaign Together in Key Swing State

President Barack Obama will appear alongside Hillary Clinton next week in the key swing state of North Carolina. It will be the first time the president campaigns with the presumptive Democratic nominee during this election cycle.

The pair, who went head-to-head in 2008's divisive Democratic primary and later became political allies when Obama won the nomination, will appear together in Charlotte, North Carolina, on Tuesday, July 5. They will "discuss building on the progress we've made and their vision for an America that is stronger together," according to a Clinton campaign release.

Obama formally endorsed Clinton earlier in June after declining to take sides during much of her primary battle with Vermont Sen. Bernie Sanders.

Clinton and Donald Trump are in a tight race in the battleground state, which has voted Republican in eight of the last nine presidential elections. Obama was the lone Democratic win, when he edged John McCain in the state by just 0.3 percent in 2008. He lost the state by 2 percent to Mitt Romney in 2012.

A RealClearPolitics average of state polling has Trump with a 1.3-percent edge over Clinton, and the three most recent general election polls have all been within the statistical margins of error.
