There are currently two legalization campaigns gathering signatures for the 2014 November ballot.

Oregon will likely be the next state to legalize marijuana this November. One or more marijuana legalization initiatives will potentially soon qualify for the ballot, and a new SurveyUSA poll of likely voters for KATU-TV found a narrow majority supports legalization.

The poll found that 51 percent of people who are likely to vote this November in Oregon support the idea of legalizing marijuana use for adults with the state taxing and regulating it. Only 41 percent oppose legalization.

Not surprisingly, there is a huge generational divide. Young voters support legalization by 70 percent, but 58 percent of senior citizens oppose it. Similarly, there is a big partisan divide with the two sides being almost exact mirrors of each other. Two thirds of Democrats are in support while two thirds of Republicans oppose it. The younger and more liberal the turnout is this November, the better it will be for legalization.

It should be noted that the poll only asked if voters would in general support the idea of a marijuana legalization initiative this November, since there are two different initiatives both trying to make the ballot. Using the exact language that will appear on the ballot in the poll can change the overall level of support.
