On Monday, "Morning Joe" host Joe Scarborough revealed that the Newtown shooting made him change his opinion on gun control entirely. More:

I knew that day that the ideologies of my past career were no longer relevant to the future that I want, that I demand for my children. Friday changed everything. It must change everything. We all must begin anew and demand that Washington’s old way of doing business is no longer acceptable. Entertainment moguls don’t have an absolute right to glorify murder while spreading mayhem in young minds across America. And our Bill of Rights does not guarantee gun manufacturers the absolute right to sell military-style, high-caliber, semi-automatic combat assault rifles with high-capacity magazines to whoever the hell they want.

It is time for Congress to put children before deadly dogmas. It’s time for politicians to start focusing more on protecting our schoolyards than putting together their next fundraiser. It’s time for Washington to stop trying to win endless wars overseas when we’re losing the war at home … For the sake of my four children and yours, I choose life and I choose change.

Scarborough, when still in Congress, was notably aligned with the NRA and previously espoused libertarian views on the issue.
