Playing Nice in Selma...But Still Need Buffers

From the NYT
"The visit to Selma, a historically rich, economically struggling city, became a proxy battle for black support between Mrs. Clinton and Mr. Obama, whose candidacy represents a threat to Mrs. Clinton’s traditional base. That competitive dynamic intensified on Sunday with the debut of Mr. Clinton on the campaign trail, six weeks into his wife’s bid, and among a bloc of voters who are at once devoted to the former president and torn between his wife and Mr. Obama.It was the first side-by-side appearance of Mr. Obama and Mrs. Clinton in the 2008 presidential campaign, and the political theater of the two campaigns overlapped repeatedly, but with a polite tone that contrasted with their political skirmishing of recent weeks."
