down ticket strength
"In the South, a Force to Challenge the G.O.P."
"The sharp surge in black turnout that Senator Barack Obama has helped to generate in recent primaries and Congressional races could signal a threat this fall to the longtime Republican dominance of the South, according to politicians and voting experts."

"But in Southern states with large black populations, like Alabama, Mississippi and Virginia, an energized black electorate could create a countervailing force, particularly if conservative white voters choose not to flock to Senator John McCain, the presumptive Republican nominee. Merle Black, a political scientist at Emory University in Atlanta, predicts “the largest black turnout in the history of the United States” this fall if Mr. Obama is the nominee."

"With the strong support of black voters, a conservative white Democrat, Travis W. Childers, scored an upset victory in that race, in a district held by Republicans since 1995. Kelvin Buck, a black state representative who helped the Childers campaign, said he saw a “level of enthusiasm and energy” that he had not seen before from black voters — significantly motivated, he said, by a recent Republican anti-Obama campaign.
The numbers appear to bear that out. In one black precinct in the town of Amory, Miss., the number of voters nearly doubled, to 413, from the Congressional election in 2006, and this for a special election with nothing else on the ballot. Meanwhile, in a nearby white precinct, the number of voters dropped by nearly half."
