From Reuter’s Obama buys half-hour of network primetime: “Barack Obama has purchased a half-hour of primetime television on CBS and NBC, sources confirmed Thursday. The Obama campaign is producing a nationwide pitch to voters that will air on at least two broadcast networks. The ad will run Wednesday, October 29, at 8 p.m. — less than a week before the November 4 general election….Larry Sabato, a political analyst and director of the Center of Politics at the University of Virginia, [said,] ‘Obama’s theme is not just change but unity, so he’s appealing to the whole nation rather than a handful of tossup states…He wants to win the popular vote by a good margin, which will enable him to govern.’”
