Politics and Marijuana Legalization Support for legalizing marijuana is much lower among Republicans than it is among Democrats or independents. One in five Republicans (21%) say marijuana should be made legal in this country, while 37% of Democrats and 44% of independents share this view. When Gallup asked this question in 1973, independents (25%) were at least twice as likely as Democrats or Republicans to support this idea. However, at the time, there were only slight differences in support between Democrats (13%) and Republicans (9%). The data also show differences by respondents' self-described political ideology. Twenty-two percent of conservatives feel marijuana should be made legal, compared with 36% of moderates and a majority of liberals (54%). Maybe if we elect a ton of liberals and independents into office, cannabis legalization would be much more likely to happen. Who Supports Marijuana Legalization?
