They just keep on coming--polls showing a majority nationwide in favor of marijuana legalization. The latest is from NBC News and the Wall Street Journal.

In the WSJ.NBC poll (the marijuana question is question 20) released yesterday, a solid 55% majority said they favored allowing adults to buy small amounts of marijuana from state-licensed businesses. That's in line with a slew of recent polls showing support for marijuana legalization either at the tipping point or beyond it.

The WSJ/NBC poll showed the strongest support for legalization coming from voters under 35, nearly three-quarters of whom favored it. Support declined with age: Among 35-to-49-year-olds, support was at 51%; among the 50-to-64 age group it was 49%; among senior citizens, it declined to 38%.

Democrats were strongly in favor (66%); Republicans were not (38%).

Support was steady at near 55% across education levels, from high school to post-grad.

We are living a sea change.
