The AP reports:
OLYMPIA, Wash. — Washington U.S. Sen. Patty Murray seized a fourth term Thursday, surviving voters’ backlash against Democrats nationally and weeks of relentless GOP campaign attacks on her voting and federal spending record.
Murray’s victory over Republican Dino Rossi, after three days of tallying, preserves breathing room for the Senate’s shrunken Democratic majority. Republicans made inroads there Tuesday and took control of the House for the rest of President Barack Obama’s first term.
Her win was secured Thursday as tallies pushed her lead to about 46,000 votes out of more than 1.8 million counted, or about 51 percent to 49 percent. About three-quarters of the expected ballots had been counted in unofficial returns.
