Nearly half of the young voters who in 2008 registered and cast their first presidential ballot may have not updated their voter registration, according to a new survey, a situation that could most impact President Obama considering that voting bloc helped him to victory four years ago. The finding by the non-partisan group HeadCount found that seven out of 10 young voters changed residence in the past four years, and 43 percent of those potential voters have yet to update their voter registration. The so-called âyouth voteâ is the estimated 15.5 million U.S. citizens who are 18 to 24 years old, according to the Census Bureau. Roughly 49 percent of them voted in 2008, compared with 47 percent in 2004 and an historical rate of about 40 percent. http://www.elitetrader.com/vb/thread.php?s=&action=newthread&forumid=27
