In the wee hours of Sunday morning, Iowa Democrats, meeting in the state convention in Des Moines, approved a platform plank calling for the legalization of all drugs.On Monday, however, Democratic legislative leaders made it clear they don’t embrace that position and will either run away from it or ignore the policy position adopted by party activists.“I’ve spent a good deal of my life as a substance abuse counselor, and I’m not going to support legalization of methamphetamine and illegal opioids,” House Minority Leader Mark Smith, D-Marshalltown, said.
