Who's happier?

See this IPS discussion on the debate between Sam Harris and Jonathan Haidt on liberal vs. conservatives. Then see this recent article exploring new findings on the happiness factor in liberals and conservatives. From the latter:

"It’s a finding that’s been replicated again and again: Ask political conservatives and liberals to rate their happiness, and conservatives come out ahead. [...] But a paper published in the March 13, 2015, issue of Science seemed to turn the happiness gap on its head by showing that when happiness is measured using behavioral cues, liberals come out ahead."
