An early spate of Democratic Senate retirements has put Republicans in solid shape to retake the majority in the upper chamber next year.

On the House side, Democrats need to pick up 25 seats to win back the majority and, as a starting point, Dems are targeting 14 of the most Democratic-leaning House seats held by Republican lawmakers.
Among them are freshmen Reps. Allen West (R-Fla.), Robert Dold (R-Ill.), Lou Barletta
