The hard-fought Pennsylvania Senate contest between former GOP Rep. Pat Toomey and Democrat Rep. Joe Sestak remains separated by less than a percentage point.
With about 82 percent of the vote recorded, Sestak trails Toomey by about 30,000 votes.
About 40 percent of the vote in Montgomery County — in the Philadelphia suburbs — has not yet been counted. Sestak must perform well in the city's collar counties — where voter registration is about equally divided between Republicans and Democrats — to pull out the win.
