Barack Obama to Announce VP in Illinois on Saturday - How to Attend

Illinois Senator and presumptive Democratic Nominee for President of the United States Barack Obama will return to Illinois on Saturday to announce his running mate. He'll make the announcement at the old State Capitol building in Springfield, IL. It's a National Historic Landmark famous for hosting Lincoln's "House Divided" speech. Now, the building becomes part of history again.

Obama announced his candidacy in front of the old State Capitol (photo inset) on February 10, 2007. When he clinches the Democratic nomination in Denver this month, he will be the third Illinois candidate in history to be nominated for the presidency by a major party. The other two were Abraham Lincoln and Adlai Stevenson.
