Republicans win 5 seats, but Dems lock in majority

WASHINGTON — Democrats lost US Senate seats in at least five states on Tuesday, but were guaranteed to keep their majority thanks to wins in California and West Virginia.
Republicans scored big victories, taking Senate seats from Democrats in Pennsylvania, Wisconsin, Arkansas, North Dakota and Indiana.
The net gain of 10 they needed for control of the chamber, however, eluded them.
With Republicans taking over the House, President Barack Obama will need a Democratic-run Senate to champion his legislative agenda.
