Jeffrey M. Jones at Gallup:
Majorities of Republicans and Democrats have positive opinions of capitalism, but Republicans rate it higher. Whereas roughly seven in 10 Republicans and Republican leaners have viewed capitalism positively since 2010, about half of Democrats have done so. This year, 72% of Republicans and 52% of Democrats have a positive image of capitalism.
The two partisan groups' opinions of socialism diverge even more, with 14% of Republicans and 65% of Democrats saying they have a positive image of it. Democrats' opinions of socialism have gotten slightly more positive over the years, moving from 53% in 2010 and 2012 to over 60% in the past two surveys. Republicans have become slightly less positive toward socialism than they were in the initial surveys.
