SPRINGFIELD -- Sen. Dan Duffy, a Lake Barrington Republican, said Monday he'll run for a second term in the Illinois Senate in 2012.
Duffy was first elected to the Senate in 2009, so 2012 will be his first re-election bid.
"As always, it's a team decision between me and my family," Duffy said.
Duffy has become known in Springfield for high-profile protests against some political appointees. Recently, he opposed Rep. Kent Gaffney's appointment to the Illinois House to replace the late Rep. Mark Beaubien, saying the seat shouldn't be given to an insider.
He also, like most Republicans at the Capitol, opposed the income tax hike approved earlier this year.
"My main role, I would say, is to speak out," Duffy said.
Duffy split with most in his party, though, when he voted to ban the use of the death penalty in Illinois.
Duffy is the first to throw his hat into the ring for the Senate district where he lives now.
The district includes central and southwestern Lake County, southeastern McHenry County and northwest Cook County.
