The project also tracks spending, and reports show the presidential

The nearly 18,000 Senate race ads in Wisconsin were the second-highest total in the country, behind the 25,211 ads on the Montana Senate race during the first three weeks of October.

The ad data comes from reports produced by the Wesleyan Media Project at Wesleyan University in Connecticut. The ongoing tracking project is the successor to the Wisconsin Advertising Project, which ended in 2009.

The project also tracks spending, and reports show the presidential and senate races have been lucrative for local broadcasting stations and national cable networks.

From Oct 1 through Oct. 21, the presidential candidates and supporting groups spent $8.4 million on ads. That's a 92.7 percent increase over spending during the previous three-week period, which began after the Democratic and Republican national political conventions.

As rain intensified late in the first half

But Antigua's speed began to pay off and, as has been their tendency throughout qualifying, the Americans got lax on defense. A quick burst by Peter Byers got him free in the area on right wing and when center back Clarence Goodson fell, Byers tapped the ball to an uncovered Blackstock for the equalizer.

As rain intensified late in the first half, the United States again took charge of possession, but couldn't connect. Bradleywas just off-target with a 25-yard blast in the 40th minute, his shot glancing off the right goalpost. The hosts then challenged Howard with a quick counterattack, but the veteran keeper caught the shot from Byers.

Blackstock shot wide in the final seconds of the half with the Americans off-balance in their end.
