A poll conducted earlier this month by Mason-Dixon Polling & Research on behalf of the Marijuana Policy Project finds that 76 percent of Americans want President Barack Obama to end his crackdown on medical marijuana in states where medicinal use of the plant is legal.

According to MPP's release, "Support for keeping the federal government out of state medical marijuana issues was universal across all demographics. With respect to political affiliation, 75% of Democrats, 67% of Republicans, and, notably 79% of Independents said that President Obama should respect state medical marijuana laws. Even among the least supportive group (those identified as over 65 years of age), 64% were in favor of respecting state law."

Another poll out today, this one from Public Policy Polling, finds that 65 percent of New Hampshire residents support legalizing medical marijuana.

In October 2011, the polling firm Gallup reported that for the first time 50 percent of Americans thought marijuana should be legal, while 46 percent felt that it should remain illegal.
