You must surely have noticed over the decades that the Democratic positions on various topics are supported by Science.  Or that panels of scientists endorse various liberal positions.  There is always “panel of 16 economists” who endorse the Democratic presidential candidate. 

When I was younger, I might have sought to understand it in terms like “liberal positions are more scientific (vs conservative positions that are more religious)”.  But a simpler explanation is simply that scientists as a group tend to support liberal positions. There could be many reasons for this.  One is simply that the Democrats support spending taxpayer money on funding science (and arts and many other things) and Republicans are generally for less government spending.  If your career depends on one party being in power, wouldn’t you support that party?

A friend recently shared that Washington DC, where a lot of Federal government employees live, is also heavily pro-Democrat.

I see a similar pattern in state capitals. For example, in the 2024 election, even in states that went for Trump, the capital city of the state, where a high fraction of residents are government workers, went for Harris. There are only 12 states where the capital went for Trump. These are almost all hard core red states, with the exception of Carson City, NV, which is in a swing state.

State	Capital City (or county containing it)
Alaska	Juneau
Arizona	Phoenix
Idaho	Boise
Kentucky	Frankfort
Missouri	Jefferson City
Montana	Helena
Nevada	Carson City
N. Dakota	Bismarck
OK	OK City
S. Dakota	Pierre
W. Virginia	Charleston
Wyoming	Cheyenne

Election data is only available at the county level. So, the table above is about the county containing the state capital. I’ll note that Phoenix and Carson City both went for Trump by only a narrow margin.

I’m not saying they are wrong.  Even broken clock can be right about the time sometimes.  Rather, that they have lost credibility.  Because of their relentless advocacy of the left, people don’t take scientists seriously.
