The pot question

A new poll today shows apparent support for legalization of marijuana. Poll: 41 percent support pot legalization (CBS). (Psst: 52 percent still oppose it)

Why the emphasis on the minority? Because the poll has shifted by 10 percent. Just a few months ago, another CBS poll showed only 31 percent favored legalizing marijuana.

But polls on the question tend to vary widely. In May, a Zogby poll claimed 52 percent of Americans favored legalization.
