Some of this is personality, some is local politics. The so-called establishment in Georgetown doesn't like Brooks and doesn't want growth or more business traffic - Georgetown is an old Victorian mining town that is getting a lot of money from preservation funds being generated by gambling in other Colorado towns without having to put up with casinos. A few years back, Colorado allowed small-stakes casino gambling in the mining towns of Black Hawk, Central City, Cripple Creek and Georgetown to help the economically-depressed towns to develop. Black Hawk has been completely overwhelmed by casino development and lost its historic character, Central City hasn't done much because Black Hawk is between it and Denver, and Cripple Creek, from what I have heard, has maintained some kind of balance between casino development and historic flair. Georgetown voted to not allow casinos, but still gets restoration money from the common fund - so a lot of town people would rather just get the preservation money and not worry about attracting more tourists and business, something Brooks wants to do and therefore she is a target for the NIMBY types.
However, Brooks has done a good job at making herself a target as well. She neglected to tell voters that she has some serious short-term memory problems because of a car wreck a few years ago and requires an aide to literally remember stuff for her. And, from what I have seen, she tries to abuse her powers as mayor and has pissed off the local cops with her attempts to control the police department. Hopefully, the meeting detailed in this story will end some of the hijinks on both sides...
