Wealthy Potomac businessman John Delaney (D) won a hotly contested congressional primary for the right to take on Rep. Roscoe Bartlett (R), “setting up a battle for the seat in November that will help decide control of the House of Representatives,” the Baltimore Sun reports.

Democratic leaders backed state Sen. Rob Garagiola (D) and even redrew the district to make it more competitive for him.

The race “is likely to be among the most expensive and closely watched in the country. Democrats are eyeing the district as a rare opportunity to pick off a GOP incumbent, while Republicans have vowed to vigorously defend it.”
