Democrat Cory Booker, the charismatic mayor of Newark, was the unofficial winner of a New Jersey special election on Wednesday, handily defeating a conservative Republican to fill the state's vacant U.S. Senate seat. Booker, who had been heavily favored in polls, defeated conservative Republican Steve Lonegan, a former small-town mayor, according to tallies published online by The New York Times, Politico and the Star-Ledger newspaper.

The tallies showed Booker with an 11 point lead over Lonegan with more than 90 percent of the votes counted. Booker, 44, spoke to cheering supporters in Newark where he thanked them for turning out to vote against the backdrop of the 16-day government shutdown and partisan battling in Washington.

"It would have been easy to listen to this frustrating negativity and stay home today. But here in New Jersey, more than a million people rejected cynicism and came out on a Wednesday, in the middle of October, three weeks before we have another election, to fight the cynicism," he said.
