As former Speaker of the U.S. House of Represenatives Tip O’Neill once said, “All politics is local.” Perhaps with that in mind, the Google Earth Blog has announced that Google Earth has geared up for future U.S. elections by adding “U.S. Elections Guide” and “U.S. Congressional Districts” information layers. Once you’ve downloaded the most recent version of Google Earth, you’ll be able to select layers that will display the boundaries of voting districts, local polling places, campaign finance data, links to candidates Web sites, news and other information related to the election. The layers are not available through Google Maps, so you’ll have to have access to a PC able to run Google Earth. (Hat tip to Slashdot.org and Greg Sterling at SearchEngineWatch.com.)
