WASHINGTON -- Sinister characters are scheming in a smoke-filled room, in a television ad that depicts big campaign contributors to Bob Casey, a Democrat running for Senate in Pennsylvania.
After detailing the legal troubles that each donor faces -- including an FBI investigation and jail time -- the somber narrator asks, "Where does Casey hold his campaign meetings?"
The camera pulls back to show the cigar-smoking "campaign team" -- behind bars.
That graphic, personal attack on the candidate challenging Sen. Rick Santorum (R-Pa.) is a particularly sharp-edged example of a key strategy in the Republican political arsenal as the party fights to keep control of Congress: going negative and personal, early and often.
While President Bush and national GOP leaders are attacking Democrats on such big issues as national security and America's role in the world, individual Republicans are hitting their opponents hard -- below the belt, some critics say -- on personal and local issues.
Negative campaigning is hardly new, and Democrats are dishing dirt against Republicans too. But mudslinging is crucial to the Republican plan for this year's midterm elections, because the party's hold on power will probably hinge on shifting attention from the unpopular war in Iraq and other national issues that cut against them.
"When people are looking at national issues that are not breaking our way, what you want to do is focus on your opponent," said Rep. Tom Cole (R-Okla.), a former Republican National Committee chief of staff. "You've got to play the field's conditions. They demand very tough tactics."
Cole spelled out that approach in a recent strategy memo to House Republicans: "Define your opponent immediately and unrelentingly.... Do not let up -- keep the tough ads running right up to election day. Don't make the mistake of pulling your ads in favor of a positive rotation the last weekend."
Republican incumbents this year began running attack ads earlier than ever. But the hardest-hitting are yet to come.
"You haven't seen the majority of the negative ads yet," said Carl Forti, spokesman for the National Republican Congressional Committee, where a staff of 10 has been deployed on opposition research.
The strategy rests on the widely held belief that negative political ads make more of an impression on voters than positive ones.
