Telecom immunity is not the issue. Upholding the Constitution (including 4th Amendment) and Rule of Law is. Telecom immunity is simply the means of guttting them (i.e., it guarantees that current civil suits -- the only likely means of shining a light under the rock of the Bush admin's illegal spying on Americans -- will be dismissed, hence ensuring the perps' freedom from accountability).

Obama was right when he took a stand on these issues (specifically, to oppose and support a filibuster of any bill with telecom immunity) and wrong to go back on it. It's just that simple. It's also an utterly non-partisan matter, and about as far from "extreme" as it's possible to get, impinging as it does our most core, fundamental Constitutional values and principles, i.e., precisely what make this country worth defending.
