What L.A. Chamber's endorsement of Brown plan might do

I happened to be on a breakfast panel this morning at the L.A. Area Chamber of Commerce when word came down that the organization would be endorsing Gov. Jerry Brown's budget plan, which includes the controversial five-year tax extension. The chamber tends to stay in the middle lane on policy issues (which is to say it's different from a lot of other chambers around the state) - and I pretty much found that same sensible vibe during our Q&A session (the other participants were political writer Joe Mathews and Alice Walton of the City Maven). The question, of course, is whether the chamber's endorsement of Brown's proposal will hold any sway? There's not much time to find out - March 10 is considered the deadline for cutting a budget deal that would include a special election on the tax extension. Even if that happens, the governor will have to convince California voters that the extension is a good idea. Mathews brought up the most basic question: What happens after the five-year tax extension expires in 2016? Without a wholesale restructuring - that's pension reform, campaign reform, the whole daunting package - an extra few years of tax revenue won't do that much good.
