What Happens If Washington State Legalizes Pot?

Hemera/Thinkstock(OLYMPIA, Wash.) — Washington state probably won’t influence the 2012 presidential race, but voters there could still leave the next president in a haze.

On Tuesday, Washington may very well become the first state to legalize the possession, cultivation and commercial sale of marijuana, both Republicans and Democrats say — bringing the state into apparent conflict with federal law if voters approve Initiative 502, which would allow residents over 21 to buy pot from stores licensed and regulated by the state liquor board.

If I-502 passes, it remains unclear how the president, whoever he is, will respond.

The White House declined to comment to ABC News when asked whether President Obama would seek to overturn I-502, should it pass and should he remain in office. So did Obama’s Office of National Drug Control Policy. Neither Obama’s nor Romney’s presidential campaign responded to multiple emails seeking comment over the weekend.

“We are not going to speculate on the outcome of the various ballot initiatives in each of the states,” Department of Justice spokeswoman Allison Price wrote in an email.

Representatives of both political parties in Washington told ABC News that prospects for I-502 look good.

“I have no doubt it’s gonna pass,” Washington Republican Party Chairman Kirby Wilbur told ABC News. The state GOP did not take a position on the measure, and no one raised it in an endorsement meeting, Wilbur said. “As liberal as the state is … I wouldn’t be surprised to see it at 55/45,” Wilbur said, referring to percentages of the vote for and against.

“It’s really hard to know what’s going to happen,” Washington Democratic Party spokesman Benton Strong said. “I think most of the polls look positive for it.”

Their favorable handicapping is informed partly by automated polls, considered unreliable by ABC News, that predict the measure will pass by a comfortable margin. Major pollsters have not surveyed in Washington in 2012, focusing instead on competitive presidential-battleground states.

Washington’s Republican and Democratic candidates for attorney general have pledged to defend it in federal court if it passes and is challenged, although both oppose the measure. Both men think a federal challenge is likely.

“If it does pass, and it looks like it may pass in this state, we will be exactly contrary to federal criminal law,” said Reagan Dunn, the Republican candidate, at their September debate. Dunn was referring to the Controlled Substances Act, enacted under President Nixon in 1970. “Depending on who is the U.S. attorney, depending on who is the attorney general of the United States, we are very likely as a state to be sued and challenged in federal court on this issue.” Dunn then touted his experience trying cases in federal court.

“If the voters approve the initiative, obviously my job is to defend that state law,” said Bob Ferguson, the Democratic candidate. “It won’t be easy. Anyone who says it will be easy is kidding themselves.”

If I-502 passes, possession will become legal 30 days after Election Day, but regulated commercial sale would not begin until Dec. 6, 2013, after a year-long rule-making process granted to the state’s health department. During that time, supporters hope to negotiate with the federal government and avoid a challenge.

Medical marijuana doesn’t offer a clear picture of how the federal government would respond to I-502 passing, either. A total of 17 states, including Washington, plus the District of Columbia have legalized medical marijuana, and the Obama administration’s approach to those state laws has drawn criticism from marijuana advocates. A 2009 Justice Department memo urged U.S. attorneys to avoid prosecuting medical-marijuana patients who follow state law; a later memo advocated prosecution of medical pot shops.

Regardless of whether Washington’s initiative passes, marijuana legalizers have said they will continue to push state initiatives. After major state/federal issues have arisen in court over Arizona’s immigration law and funding provisions in Obama’s health-reform law, advocates are pushing marijuana to become the next major states’ rights legal conflict.

“Only through a process of states challenging federal marijuana policy and demanding that they be allowed to regulate marijuana in a way that’s socially responsible for local communities are we also going to see a change in federal policy,” Drug Policy Alliance Executive Director Ethan Nadelmann told ABC News.

Since the candidates won’t say how they’d handle such a scenario, Washington, Oregon and Colorado — where similar initatives will also appear on the ballot Tuesday — will have to wait and see if the issue is forced.
