Hillary Clinton has re-opened her sharp attack on Barack Obama's position on guns, with a mailer in Indiana that seeks to raise questions about him with both supporters and opponents of gun rights.

The mailing -- perhaps the sharpest-edged of Clinton's five negative mail pieces in Indiana -- casts him as a typical politician, saying different things to different audiences. It also revives his damaging comments in San Francisco that small town people cling to guns.

Then, making the harsh case more broadly, the mailer asks: "What does Barack Obama really believe?"

The piece is particularly striking coming from Clinton, who has been seen for most of her career as a firm advocate of gun control, but more recently has emerged -- without dramatically shifting her stance on specific issues -- as a defender of the Second Amendment who fondly recalled being taught to shoot by her grandfather in Scranton.

CNN reported Saturday that Democratic Presidential Candidate Hillary Clinton touted her experience with guns and hunting to a crowd in Indiana:

Hillary Clinton appealed to Second Amendment supporters on Saturday by hinting that she has some experience of her own pulling triggers.

"I disagree with Sen. Obama's assertion that people in our country cling to guns and have certain attitudes about trade and immigration simply out of frustration," she began, referring to the Obama comments on small-town Americans that set off a political tumult on Friday.
