Debbie Dingell has raised more than $500,000 in a little more than a month of campaigning for her husband's 12th Congressional District seat.
The Democrat announced her campaign on Feb. 28, just after Democratic Rep. John Dingell said he'd retire from the House after the longest tenure in history.
Her campaign says 93 percent of donations came from individuals. She filed the maximum-allowed 2,000 signatures supporting her candidacy Friday with the state.
Dingell is the favorite to win the seat, but says no one is a shoo-in and candidates who think they are "get into trouble." She says she plans to do "500 coffees, teas" and "dialogues" in every city and town in the district before the November election.
