DEMS THROW PARTY OF THE YEAR; GOP NOT INVITED "Celebrities may be scarce at the Republican convention come September, but the Democrats have so many clamoring to get into their convention in Denver the week before, it's like the Vanity Fair Oscar party. George Clooney, Madonna, Kanye West, Scarlett Johansson, Susan Sarandon, Spike Lee, Quentin Tarantino and Matt Damon are just a few of the stars who want to be there … The Republicans have even engaged top William Morris agent Jeffrey Barry to try to wrangle country western stars to trek to the Twin Cities, a political source tells us. He's garnered 'Redneck Woman' singer Gretchen Wilson, the source adds, but Barry wouldn't answer questions about whether he's rounded up more."
