For a very long time, pot was not something that politicians talked all that much about.
But in recent years, public attitudes on marijuana legalization have shifted considerably -- more than half of all Americans thought pot should be legal in Pew polling done earlier this year -- and, with them, politicians' stances on cannabis.
Kentucky Sen. Rand Paul has openly speculated about changing his party's stance toward pot. New Jersey Gov. Chris Christie signed a measure that would allow medical marijuana for children. This week, White House deputy press secretary Josh Earnest even got a question about pot.
We talked to Marijuana Policy Project's Dan Riffle about changing attitudes toward pot and what it might mean for policy in the country.
