The Democratic Party's convention in Denver next month will really be a party, a line-up has just been announced, and it sounds more like a concert tour sponsored by Live Nation than a political convention. Kanye West, N.E.R.D., and Wyclef are expected to perform, and tons of Obama-loving stars — Scarlett Johannsen (of course), Ben Affleck, Forest Whitaker, etc. — will be in attendance. No word yet on who will be rocking it out at the Republican National Convention in St. Paul, although I'm sure JJ Walker would happily accept an invite. [WP]
