As I’ve written above, the two groups may not be representative of the LW community or the US population. But within each group the differences were statistically significant, so the question about their origin would be valid in any case.
In the “optimate” vs “populare” case, the difference was significant at about 2.5 sigmas.
I don’t remember the exact values in the “left” vs “right” case, but it was over 10 sigmas.

If the significant means statistical significance, then what’s the p-value?
