Just got another reply from Maria Cantwell. She's backtracking a bit. Or at least her language is. She's probably rabidly anti-gun. I've seen somewhere, I think a non-partisan on the issues .org website with her on record as believing there is no right for John Q Public to own firearms. In her latest reply she mentions Feinstein's bill, but doesn't say she'll support or oppose it. She mentions new common sense laws, as well as enforcing new ones, and she's starting to talk about putting mental health in the discussion. I suspect she's getting the statistics on which side her bread is buttered on in this State and is trying to find just how far she can push it.
Regardless, I think a lot of the anti's are backtracking.
