Turnout in Illinois' primary ranges from low in Democratic areas to steady in Republican strongholds.

In staunchly Democratic Cook County, turnout appears light.

But numbers in heavily Republican DuPage County are better.

A spokesman for DuPage County's election commission, Dan Curry, expects final turnout of between 36 and 40%. He says that would be only a slight drop from 44% in 2008.

In western Illinois, Adams County Clerk Georgia Volm says final turnout should be around 20%, down from nearly 34% four years ago. She says a lack of a meaningful Democratic primary explains the drop.

DuPage County voter Mark Plunkett says he's disturbed by the low turnout elsewhere. He voted for Newt Gingrich Tuesday and says there's too much at stake not to vote.
