Control over the U.S. House of Representatives still hangs in the balance, teetering between a Republican or Democratic majority with just over two dozen races left to be called. The Republicans won control of the U.S. Senate early Wednesday. Republican leaders are projecting confidence that they will keep control of the U.S. House as more races were decided in their favor Thursday, while Democrats insist they still see a path toward the majority and sought assurances every vote will be counted.
