OK keep in mind the above ranking is clearly for just the official 'City of' not for the metro area (if St. Louis Metro were included, it would move quite far up the list - much bigger than New Orleans, Kansas City, Milwaukee, and others).
So, by that definition St. Louis is quite liberal, but it is only about 350,000 out of a 2.4 million metro.
