CHICAGO (AP) -- Republicans say they're not giving up on Illinois even though Democrats Barack Obama and U.S. Sen. Dick Durbin breezed to election Tuesday.
And they won in many areas that have been traditionally Republican.
But GOP Sen. Christine Radogno of Lemont says state affiliations are cyclical and her party's improved campaign tactics helped prevent the loss of state Senate seats -- although it lost three in the House.
Exit polls conducted for The Associated Press and television networks show that about half of all voters now identify themselves as Democrats, up from about two in five the past two decades.
The exit poll of 1,389 Illinois voters was conducted for AP by Edison Media Research and Mitofsky International in a random sample of 25 precincts statewide. Results were subject to sampling error of plus or minus 4 percentage points, higher for subgroups.
