Yes they most certainly do.  All you have to do is look at their past actions and statements Feinstein passed and was implementing a gun BAN in San Francisco where the courts promptly struck the law down as unconstitutional.   She has since introduced more than 50 incremental bans.   And no she is not alone.   The gun ban groups have just learned that if you try to call it anything other than a gun ban more people will support it than would support it if you called it what it is.
