In an answer on politics.SE, a Northwestern University study was highlighted, whose main findings included:
more Democrats than Republicans think astrology is scientific
Using Fisher’s Exact Test, conservative Republicans are significantly more likely than other groups combined to reject astrology as not scientific (p<.0005). The same is true of conservatives compared to non-conservatives (p<.0005) and Republicans compared to non-Republicans (p<.0005). Likewise, Democrats are less likely to reject astrology as unscientific than others (p<.0005).
fewer Democrats than Republicans think the earth revolves around the sun.
...in 2012 a majority of Democrats (51.4%) could not correctly answer both that the earth revolves around the Sun and that this takes a year. Republicans fare a bit better, with only 37.9% failing to get both correct.
One thing that does look a little dubious is that that this study was penned by a law professor. I'm also unsure if it has been published in a peer-review venue.
Are the results of this study consistent with other similar studies on such matters?
