Did Obama promise last year to ban all semi-automatic guns during his first year as president?

For the wingnuts who believe everything that arrives in their email box:

A widely circulated e-mail quoting Obama is baseless and almost certainly fabricated. He does support reinstatement of the expired "assault weapons ban" but isn't calling for a wider ban on all semi-automatic weapons. He said repeatedly during the campaign, "I am not going to take your guns away."
