I have to disagree with you on Joe Riley. He courageously led a march from Charleston to Columbia to demand that the flag be taken off the statehouse dome. He was the highest profile politician in SC to take such an aggressive stand.
I know we are talking relative relationships, but in a state where the rebel flag flies conspicuously in rural areas Charleston is much more liberal. How else to explain a lesbian candidate getting 48% of the vote in a Congressional race?
See here about Riley's march:
April 7, 2000
Long March Ends in South Carolina,
But Little Time Is Left to Lower Flag
COLUMBIA, S.C., April 6 -- By his own estimate, Mayor Joseph P. Riley Jr. of Charleston had walked nearly 275,000 steps when he turned the corner onto Main Street this morning and finally saw the Confederate battle flag that he and hundreds of others had been marching since Sunday to remove.
Since setting out from Charleston, 120 miles away, he had endured death threats, roadside obscenities, wet clothes and blisters so painful that they needed medical attention. And for all that, there was only a slim hope that the state Legislature would vote to remove the flag from atop the Statehouse dome before the end of the year's session.
