The grandson of the late U.S. Rep. Julia Carson was chosen in a special election Tuesday to succeed her in Indiana's 7th District in the House of Representatives.
Democrat Andre Carson defeated Republican Jon Elrod. His victory is the second special election win in less than a week by House Democrats.
Over the weekend, Rep. Bill Foster (D-Ill.) upset his Republican opponent to claim the seat once held by former Speaker Dennis Hastert (R-Ill.). Foster was sworn-in Tuesday.
Democrats expected Carson to win his seat.
Carson becomes one of only two Muslims in Congress. His grandmother, who died in December of lung cancer, was the first black to represent Indianapolis in Congress.
Carson will represent a district that covers most of Indianapolis for the remainder of the year.
But he could face a tougher challenge in the fall in Republican-trending Indianapolis. Little-known GOP politician Greg Ballard came out of nowhere last November to knock off Democratic Mayor Bart Peterson.
Rep. Chris Van Hollen (D-Md.), chairman of the Democratic Congressional Campaign Committee released a statement congratulating Carson.
"He is a tireless leader for the children and working families of Indianapolis," he said.
"I am grateful to the Congressional Black Caucus, Senator Evan Bayh and Indiana’s Democratic Congressional Delegation for encouraging the people of this district to vote for change by supporting Andre Carson. Andre Carson will be a tremendous asset to our Democratic Caucus as we fight to strengthen our economy, end the war in Iraq, and restore the American dream to America’s middle class families.
"We look forward to working with Andre Carson and local and state Democrats to ensure a Democratic victory in November."
