There has been an increase in Taliban activity because of the upcoming September 18th national elections. However, it appears that number of Taliban operating is not large. Nearly all the Taliban go out in armed groups, usually no more than a few dozen men. This is neccessary in order to make sure the Taliban have the firepower advantage in case any village or neighborhood resists them (many of the local men grabbing weapons and coming out). But such large groups are easier to spot. The police and army have more radios and trucks now, and are out there looking for the Taliban groups. If spotted, American air power and infantry reinforcements (via helicopter) are available.
The Taliban, despite boasts to the contrary, were unable to disrupt the last elections, and appear on their way to repeating that dismal performance. Many Taliban tribal leaders have since switched their allegiance to the government.
Meanwhile, Pakistan has moved several thousand more troops to the Afghan border, apparently to deal with an increase in Taliban activity.
