Obama is given security by the secret service much earlier than most "presidential hopefuls."
I like the lead in the Chicago Sun Times, it is very catchy and highlights the unusualness of the story:
"Major presidential candidates and their families usually get Secret Service protection within 120 days of the general election.
That's 551 days away, so how did Obama get protection?"
But that report on the whole, is mostly just a look at quick explanation of the issue, without much background reporting. The New York Times, gives a much broader look at the situation. It gives some reasons why Obama is recieving protection, including race and the big crowds he draws to speeches.
They interviewed his wife who gave good background into the risks of running for president, or being the wife of the person who runs for president.
It also tells us other people who have recieved protection early, and the reasons why. This also gives us a broader look at the subject.
