A look at some of the presidential candidates' positions on gun control:

• Sen.

Hillary Rodham Clinton, D-N.Y.: Voted for ban on assault-type weapons and to require background checks at gun shows. Calls for renewing the ban, which expired in 2004. Favored leaving gunmakers and dealers open to civil suits. In 2000, supported proposals for a federal requirement for state-issued photo gun licenses, as well as a national registry for handgun sales.• Sen.

Barack Obama, D-Ill.: Voted to leave gun-makers and dealers open to suit. Also, as Illinois state lawmaker, supported ban on semiautomatic weapons and tighter state restrictions generally on firearms.• Sen.

John McCain, R-Ariz.: Voted against ban on assault-type weapons but in favor of requiring background checks at gun shows. Voted to shield gun-makers and dealers from civil suits. "I believe the Second Amendment ought to be preserved — which means no gun control."
