I think it was like 36 days after the 2000 election that Al Gore finally conceded. And you know what, not one democrat complained about it. Repeat, not one democrat complained about it.
BTW, I had been voting democrat through the 2000 election. I voted for Al Gore. It was when the demcrats put up John Kerry in 2004 that I knew the dems were getting out of whack. To far left. I didn't leave the dems. They left me.
