"The poll of 400 likely voters -- 39 percent Democrats, 33 percent Republicans and 28 percent independents -- found that only 23 percent believed the nation is on the right track; 45 percent prefer a Democratic representative to a Republican; and when asked if they would vote to re-elect Leach, 38 percent said yes, 23 percent said they would consider someone else and 25 percent said they would vote to replace him. The poll has a 4.9 percent margin of error.  In a head-to-head ballot test, Leach received 47 percent of the votes in the survey, and Loebsack tallied 33 percent."

So Loebsack has yet to close the sale - but voters are shopping around.  I don't know how much more convincing folks need: the Democrats can beat Leach.
