Corruption named as key issue by voters in exit polls - CNN.com: "(CNN) -- By a wide margin, Americans who voted Tuesday in the midterm election say they disapprove of the war in Iraq.

But when asked which issue was extremely important to their vote, more voters said corruption and ethics in government than any other issue, including the war, according to national exit polls.

A large majority of voters also disapproved of how Congress and President Bush are doing their jobs. However, Bush fared slightly better on that score than members of the GOP-led Congress.

And defying the traditional political maxim that 'all politics is local,' 62 percent of voters said national issues mattered more than local issues when deciding which House candidate to pick.
