Publicola had a good take on the Board elections based on Sherry Carr challenger, Kate Martin, who says that some of Sherry's high donors from her last election "own her."
What is interesting is that these are some of the city's heaviest hitters and Sherry says she doesn't know most of them. If out of $149k of donations from my campaign, $84k came from 8 couples, I, as a candidate, might want to reach out to those people and meet them. (I would just feel weird accepting that much money and not even talking to them.)
The article also reports that so far Carr has raised over $9k and Martin $1500.
Update: I would like to add that Carr had most of her donations in her first election come in under $100 and the trend is continuing in this one. I suspect that is true for most candidates but it's possible to look it up.
