City Council Election Demographics: Arroyo's Rise

In today's Globe, Andrea Estes and Lisa Wangsness discuss how Council results signal voting shift:

Arroyo finished second overall behind Flaherty in Tuesday's election. But according to a Globe analysis of the polling results, the city's first Hispanic councilor at large won 11 of the city's 22 wards while Flaherty won only six in predominately white areas, including Charlestown, Dorchester, and his home neighborhood of South Boston.
The results appear to reinforce the belief of some candidates and political observers that voting patterns and preferences in Boston no longer automatically favor traditional candidates, who have been more typically white males, often with pedigrees in the city's Irish political establishment.
Challenger Sam Yoon -- the city's first Asian-American council candidate, who placed a strong fifth -- did well in the same neighborhoods as Arroyo, including Beacon Hill, the South End, Roxbury, and Jamaica Plain. Yoon also placed first in the ward that includes Chinatown and the North End.
An endorsement by Speaker Salvatore F. DiMasi of the Massachusetts House of Representatives was seen as helping him in that neighborhood. Patricia White, the campaign's only woman, also did well in some of the same sections of the city as Arroyo.
During the final weeks of the campaign, when the mayor's race is likely to draw attention among more liberal voters, Arroyo, Yoon, and White believe they have nowhere to go but up.

Of course, the Globe wants to talk about who's going to run for mayor, as they've already discounted this year's race. Hacks!
