What kind of campaign did Deegan run to get this kind of crossover support from Republicans?
Not much of one; she didn't need to. She was far and away the most well-known candidate due to her prior news work and charity activities. The charity activities are worth highlighting especially; it was very good for her political career that her charity's marathon (the biggest annual marathon and charity event in the city for 15 years) is called the DONNA marathon. Lots of positive name recognition.
Ah.
I can see that translating into a good result.
