Before the mid-term elections Americans visited more then usual political websites and gambling sites. Gambling sites saw a rise due to interest in the World Series of Poker. But one could also bet on the outcome of the mid-term elections, so some might have visited gambling sites more for that reason.
Online gambling has always been strong in the US even after it was banned in 2006. Legislation changes are being discussed but no major changes have been enforced yet. After the ban interests in gambling remained high and many land-based casinos are now looking to move online. Poker has been especially popular. Playing at a casino online is usually seen as safe and secure. Many websites offer a good casino bonus and promotions.
