The Hotline’s Reid Wilson, September 13: “The DCCC is readjusting advertising buys in key districts across the nation, including in Arizona, where party strategists say incumbent Reps. Ann Kirkpatrick (D), Harry Mitchell (D) and Gabrielle Giffords (D) are running stronger than expected campaigns. Mitchell is going hard after ex-Maricopa Co. Treasurer David Schweikert (R), who had to spend most of his campaign cash on a tough primary race.”

The Hotline’s Reid Wilson, today: “The DCCC will also begin running ads defending Reps. Harry Mitchell (D-AZ), Sanford Bishop (D-GA), Frank Kratovil (D-MD) and Kathy Dahlkemper (D-PA). Both parties see Mitchell locked in a tough rematch with former Maricopa Co. Treas. David Schweikert (R).”

I point this out not to mock Reid Wilson, who’s a fine reporter, but simply to illustrate the DCCC’s implausible claims of confidence. You might even say they come with an expiration date or something.
