CARMEL, IN (AP) - Indiana's longest-serving congressman has a fight on his hands as a crowded field of primary challengers aims to send him packing.
Republican Rep. Dan Burton faces four GOP challengers in Indiana's May 4 primary, including a state representative and a former party leader.
All say it's time to bring a fresh face to Washington and that Burton's 28 years on Capitol Hill are enough.
The 71-year-old Burton says he doesn't know how much longer he wants to serve in Congress but believes he still has work to do in Washington.
Burton has represented the district that now covers suburban Indianapolis and stretches north to several rural counties around Kokomo and Marion since 1982.
