OPPORTUNITY KNOCKS. "Dems rally for Obama at Ohio congresswoman's memorial." Quick, call out the Republican mourners-in-absentia. The schtick they used in 2002, when they denounced Paul Wellstone supporters who paid tribute to the late Senator's political causes at his memorial, may work again. Everything's in place: Some Democratic splitters are already on it, and Free Republic and Lucianne Goldberg are roiling the swamps. All that's needed is a credible mainstream figure like Peggy Noonan to don the mantle of propriety and cry "shame." (No, this guy doesn't count, but he's got the right idea.)

The fact that the office at issue this time is not the same one held by the deceased makes no difference. It's a national election, and every little helps.
