You’re caring less and less about Barack Obama and Hillary Clinton! These six weeks between March 15’s Texas and Ohio primaries and April 22’s Pennsylvania contest have Americans fatigued. Even crazy Internet-using Americans! That’s why traffic to both BarackObama.com and HillaryClinton.com dropped last month, after seeing record spikes in February. Visitors to Barack’s site dropped 33 percent to ~2 million, while Hillary’s supporters stopped coming by about 28 percent, down to 1 million, according to Compete.com. No worries though: John McCain, who may or may not know how to use the electronic mail, has seen web traffic plunge 38 percent to a mere 500,000 visitors.
