The DCCC launched a radio ad and robo-call campaign today, targeting eight vulnerable House Republicans over their votes against the expansion of the S-CHIP program, which President Bush has promised to veto.

The ads will be targeted against Reps. Steve Chabot (OH-01), Thelma Drake (VA-02), Tom Feeney (FL-24), Sam Graves (MO-06), Joe Knollenberg (MI-09), Randy Kuhl (NY-29), Jim Saxton (NJ-03), and Tim Walberg (MI-07).

The DCCC is hoping to turn the vote into a major campaign issue, and the available polling is very favorable to that view — voters side with the Democrats against the President by a 60%-35% margin on this issue.
