Fear of the politician with the unusual name and look did not end with last Tuesday’s vote in this rural red swatch where buck heads and rifles hang on the wall. This corner of the Deep South still resonates with negative feelings about the race of President-elect Barack Obama.

What may have ended on Election Day, though, is the centrality of the South to national politics. By voting so emphatically for Senator John McCain over Mr. Obama — supporting him in some areas in even greater numbers than they did President Bush — voters from Texas to South Carolina and Kentucky may have marginalized their region for some time to come, political experts say.

The region’s absence from Mr. Obama’s winning formula means it “is becoming distinctly less important,” said Wayne Parent, a political scientist at Louisiana State University. “The South has moved from being the center of the political universe to being an outside player in presidential politics.”
