The news article goes on to say:
The Secret Service said that this is not the result of any specific, credible threat against Obama, but they will admit that the campaign has received hate mail, calls, and other "threatening materials." They said the request stemmed from what one called the "cumulative effect" of a heavier campaign schedule, larger crowds and "just the growing perception internally" that it was time to take additional security precautions that are best suited for the Secret Service.
plez sez: i like Barack Obama and i believe he has the vision necessary to change the direction of this country. i am glad that he will begin to receive the protection he needs to ensure that he makes it through the primary season alive. it is also a sad day in America when someone who stands for what is good and right cannot spread a message of hope without fear of reprisals. unfortunately, America continues to harbor an ugly underbelly of hate and ignorance (i can only imagine what hateful things have been said about Obama and his family).
i pray for the life and vitality of Barack Obama and his family as i pray for America; i cannot wait to cheer his Inaugural Address!
