Poll: Grassley support down but still strong

Posted:

DES MOINES (AP)--A Des Moines Register poll show support for U.S. Sen. Charles Grassley slipping but still strong, with 57 percent approving of the five-term Republican.

Grassley's numbers are strong considering voter discontent with incumbents amid the country's economic problems, but they're down significantly from the 75 percent approval he had in a Register poll earlier in the year.

In a matchup with Democrat Roxanne Conlin, the most well-known of three Democrats seeking their party's Senate nomination in 2010, Grassley led 57 percent to 30 percent.

The poll, published Monday in a copyright story, was conducted by Selzer & Co. based on telephone interviews of 800 Iowans age 18 and older. The poll has a margin of sampling error of plus or minus 3.5 percentage points.
