After epic presidential campaign, voters go to polls

The 2008 race for the White House fundamentally upended the way presidential campaigns are fought in this country. It has rewritten the rules on how to reach voters, raise money, organize supporters, manage the news media, track and mold public opinion, and wage political attacks. Among the biggest changes this year is the intense new interest in politics, reflected in jumps in voters registration, early voting, and attendance at rallies.
