The Dems say the carbon tax initiative is too conservative, as do many environmental groups and unions.

Conservatives and Libertarians who support the tax include the Cato Institute, the American Enterprise Institute, the American Action Forum, the Hudson Institute, Bob Inglis' Energy and Enterprise Institute, Arthur Gaffer, David Brooks, and George Schultz.

So the LWV is supporting a position that offends some of the left and is supported by some of the right.  Sounds to me like they're doing pretty well at their charter purpose of being non-partisan on the issues.
