Not sure about Webb, but the gun control issue is getting interesting.
He quit (”withdrew”) in October. His comments are interesting:

“Some people say I am a Republican who became a Democrat, or that I often sound like a Republican in a room full of Democrats or a Democrat in a room full of Republicans,” he said. “I fully accept that my views on many issues are not compatible with the power structure and the nominating base of the Democratic Party.”
Asked if he is still a Democrat, the former Ronald Reagan administration appointee replied: “We’ll think about that.” He also said he has no plans to endorse a candidate of either party.
