(CNN) – Some unlikely faces make an appearance in a new Web ad from Republican John McCain: Democrats Hillary Clinton, John Edwards, and Barack Obama.
In the spot, all of them mention the Arizona senator's name, while the on-screen text asks: "What keeps Democrats up at night?"
It also scrolls through clips of various pundits who say the Democratic Party most fears McCain as the Republican nominee.
The ad comes on the heels of this week’s CNN Democratic in South Carolina debate, where McCain’s name was frequently invoked on stage.
"Democrat Senators Hillary Clinton, Barack Obama and John Edwards said John McCain's name 15 times during the course of their hour and a half-long debate this week," McCain spokeswoman Jill Hazelbaker said in statement. "Why? They fear John McCain most because he's the one candidate who can rally the conservative Reagan Coalition while appealing to independent voters to win in November."
In the most recent CNN poll of hypothetical general election matchups, McCain was the Republican who performed best against any of the major Democratic candidates - in a statistical tie with either of the party’s presidential frontrunners, Hillary Clinton or Barack Obama.
