Obama's officially in

Illinois Senator and traditional media darling Barack Obama officially launched a campaign to seek the Democratic nomination for President of the United States today, filing paperwork to create a presidential exploratory committee that will allow him to fundraise and set up his campaign.

Obama's announcement is not a surprise, but his entrance into the race will change the dynamic. If Obama doesn't win in the primaries and caucuses, look for him to become a likely vice presidential choice. His presence on the ticket would greatly strengthen the presidential candidacy of whoever does capture the nomination.
