Cindy Chavez is a people-uniter. How else could one explain why so many incongruous political actors of varying stripes are singing Kumbaya as they work to defeat her in the county supervisor race to replace George Shirakawa Jr. Progressives and conservatives in Silicon Valley are teaming up to battle the Chavistas, and it’s causing some friction for top opponent Teresa Alvarado as she stitches together a coalition. Apparently, some Chamber of Commerce partisans weren’t thrilled with Alvarado’s choice of political organizer, former Labor Temple soldier and occasional San Jose Inside columnist Peter Allen as her campaign manager. Allen had butted heads with independent expenditure tree shaker Vic Ajlouny during the 2012 City Council race in Almaden. The two were on opposite teams in the Johnny Khamis-Robert Braunstein battle, but in this go-around, both fell into the anti-Chavez axis. Since labor pushed Alvarado out of its camp with sole endorsements, Teresa has been courting the business community vote. She’s since slid Allen aside, choosing Magdalena Carrasco, an East Side school board member and fellow Latina Democrat who’s also fallen out of favor with the South Bay Labor Council. A few weeks ago, Allen was reassigned to work on other campaigns with Alvarado’s consultant Leo Briones, a noted political strategist and part-time poet. Allen, however, says that any talk of calamity couldn’t be further from the truth, as titles are irrelevant in a compacted race and he still holds a role in the campaign’s communications work. But Allen’s continued presence could continue to irritate the Chamber and San Jose Mayor Chuck Reed, both of whom endorsed Alvarado and have little affection for Allen’s outspoken views and former association with the labor union organization.
