Are there some specific national or statewide elections in which you are interested in following tonight while you are surfing the net? Go to cnn.com and click on Track Your Races. You'll be able to designate up to 35 races on which you will receive regular updates. This is especially useful for sometimes-hard-to-find statewide information on Senate, House, Governor or ballot elections.
One catch: the updates will only be available to you on the cnn site, so you'll have to leave a tab open for cnn.
