Maybe if Trump blasts Murkowski enough, she really will go Jim Jeffords. As I said yesterday, she pretty much hates party leadership after they supported a Tea Party loon over her in 2010. I got bored once and watched a Dan Rather interview where she seethed about it, and her eyes looked angrier than usual.
Maybe Sue Collins can channel her predecessor and Grandmother of the Moderate Darlings Margaret Chase Smith and deliver a modern Declaration of Conscience speech against Trump. Except she would take forever to read it, people would get bored and call her a snowflake, and nothing would happen.
