This is pretty fascinating really but understandable when the conservative side of American politics seems to eschew science in favor of faith and deliberately underfunded much needed and relevant scientific research.
Most scientists identify as Democrats (55%), while 32% identify as independents and just 6% say they are Republicans. When the leanings of independents are considered, fully 81% identify as Democrats or lean to the Democratic Party, compared with 12% who either identify as Republicans or lean toward the GOP. Among the public, there are far fewer self-described Democrats (35%) and far more Republicans (23%). Overall, 52% of the public identifies as Democratic or leans Democratic, while 35% identifies as Republican or leans Republican.
Majorities of scientists working in academia (60%), for non-profits (55%) and in government (52%) call themselves Democrats, as do nearly half of those working in private industry (47%).
