Vice-President Dick Cheney will arrive in Davenport Monday with approval ratings in about the same place as the president's -- in the toilet. But his target audience on this visit is the minority who approve, and within that minority it's those with enough money to cough up $500 to $1,000 to listen to the vice president explain what a great congressman Mike Whalen would make. The invitation-only reception at the home of Chuck and Jodi Ruhl will be but a small part of the high-powered money-raising effort Quad-Citians will see between now and November as congressional contests for open seats on both sides of the river turn into dollar-driven slugfests.
