Name one prominent democrat ever to stand up for the 2nd amendment?

Responding to a question about whether he would support a renewal of the Federal Assault Weapons Ban, which outlawed the manufacture of certain semiautomatic firearms from 1994 to 2004, Senator Begich said he is “not interested.”
Congressman Heath SchulerIn response to the Arizona shooting rampage, NC Congressman Heath Shuler has confirmed that he will carry a gun himself for protection at state public events. “I, like many of my constituents and staff in Western North Carolina, strongly support the Second Amendment and do exercise our right to legally and safely carry a firearm."
Senator Jon TesterIn 2008, Senator Jon Tester pushed the US Supreme Court to strike down Washington, DC's long-standing ban on gun ownership. The Court agreed and found the restrictions unconstitutional in Heller v. District of Columbia. In 2009, Senator Tester filed a major "friend of the court" legal briefing to convince the Supreme Court to strike down state and local government restrictions on gun ownership. The Court struck down the restrictive gun laws in a decision in McDonald v. City of Chicago.
