At least John McCain knows what he'll be up against in the general election. With the Democratic candidates otherwise occupied and six months to go before the presidential vote, there are already two ads on the air that use McCain's "100 years" remarks on Iraq to paint him as a standard-bearer for President Bush's policies.

MoveOn.org today announced the launch of "Candles," which uses the image of a birthday cake with a century's worth of burning candles to characterize McCain's plan for Iraq as dangerously open-ended. "One hundred years in Iraq?" an announcer says. "And you thought no one could be worse than George Bush." "Candles" joins a similar spot put out earlier this week by the Democratic National Committee.

MoveOn is running the ad on nationwide cable, as well as in New Mexico and Iowa -- two likely swing states where McCain has already begun airing general election ads. Republicans have protested that Democrats and outside groups are taking McCain's remarks out of context, but they may have to get used to it. The fact that two ads are already deploying the "100 years" charge against him suggests the soundbite -- as well as the picture of McCain embracing Bush that closes MoveOn's ad -- will only continue to haunt the Arizona senator in the coming months.
