U.S. Sen. Patty Murray, a Democrat, had consistently won re-election by healthy margins in her three decades representing Washington state. This year seemed no different: By midsummer, polls showed her cruising to victory over a Republican newcomer, Tiffany Smiley, by as much as 20 percentage points.
So when a survey in late September by the Republican-leaning Trafalgar Group showed Murray clinging to a lead of just 2 points, it seemed like an aberration. But in October, two more Republican-leaning polls put Murray barely ahead, and a third said the race was a dead heat.
As the red and blue trend lines of the closely watched RealClearPolitics average for the contest drew closer together, news organizations reported that Murray was suddenly in a fight for her political survival. Warning lights flashed in Democratic war rooms. If Murray was in trouble, no Democrat was safe.
