In a 1996 questionnaire, he answered "Yes" to the question, "Do you support state legislation to ... ban the manufacture, sale and possession of handguns?" Politico reports on this, and goes on to say:

A week after Politico provided the questionnaire to the Obama campaign for comment, an aide called Monday night to say that Obama had said he did not fill out the form, and provided a contact for his campaign manager at the time, who said she filled it out. It includes first-person comments such as: "I have not previously been a candidate."

The campaign said his views have been consistent, and points out that his positions have always been more nuanced than can be conveyed in yes-or-no answers.

Obama, who makes an issue of his opponents' consistency in the presidential race, has tempered many of those 1996 views during his quick rise to the pinnacle of American politics. He now takes less dogmatic positions many of those hot-button issues -- in the view of some Democrats, he abandoned the stands as he rose through the ranks....

On handguns, his campaign said he has consistently been for "common-sense limits, but not banning" throughout his 11-year political career.

The Hillary Clinton campaign responded:

Barack Obama's campaign is on the defensive about his electability today in the face of a new CBS/New York Times poll showing voters find Hillary Clinton far more electable and a news report showing Sen. Obama previously held positions -- such as banning all handguns -- that he no longer claims to espouse.
