It's a common assumption that teenagers are a group of loud, unruly, and often generally uninformed people. They would rather watch MTV than CNN, rather read Cosmopolitan or Sports Illustrated over Newsweek. They can name who hosts SportsCenter but have no idea who replaced Tom Brokaw on the "NBC Nightly News."
Without the Ohio, Texas, and Rhode Island results...
Obama: 1,386 delegates
Clinton: 1, 273 delegates
Some other things to ponder:
According to an anchor on CNN, Texas talk radio seems to be encouraging Texan republicans to vote for Clinton.
Even if Obama or Clinton won all of the remaining states, neither could mathemathically win the nomination before the convention (the race would come down to super delegates). As another anchor put it from Clinton's perspective: "It's not about mathematics, it's about...momentum."
