President Obama will make a campaign stop at Loudoun County High School on Thursday, his latest foray across the Potomac River into battleground territory.

Doors will open for the event at 5:30 p.m., according to an Obama campaign official. Tickets will be distributed Tuesday at 6 p.m. at the school as well as at the Obama campaign’s offices in Leesburg and Sterling.

The stop is part of a two-day swing-state campaign tour that will also take Obama to Orlando, Fla., and Akron, Ohio. Obama has made several visits to Virginia in both official and campaign capacities, including a July 13-14 swing that included several stops. Mitt Romney (R) visited Virginia in June and will most likely be back in the state soon.

Loudoun — whose population is becoming increasingly large, diverse and affluent — is considered particularly crucial in November, as Obama in 2008 was the first Democrat to win it in a presidential contest in more than four decades.
