Non-college educated in university towns/counties

[King of Kensington]

To what extent does the progressive political culture of college or university towns impact the voting patterns of the non-college educated in the area?

Looking at some election results in Ontario, an interesting thing to note is that the university town of Kingston was NDP in a sea of conservative blue Eastern Ontario.  But looking at some nearby exurbs or rural areas they also went NDP, and these don't have particularly educated populations.

Is there a similar phenomenon say, around Madison or Ithaca?

Madison had huge swings towards Trump in the Eastern Side which is more WWC before these areas were solidly democratic as other areas of Madison.

Madison and Ithaca's surrounding suburban and rural areas are great examples of the phenomenon you describe. Almost all of the municipalities in Dane (Madison) and Tompkins (Ithaca) counties voted for Hillary, including the ones with very low populations and no visible signs of urban development. Of course, plenty of college-educated folks live in these areas as well due to their proximity to the main college towns nearby, but they are mixed in with those without college degrees. I can see this phenomenon up close around the main UNH campus in Durham. Durham is an intensely Democratic town populated by faculty and people with degrees, however there is a significant population of non-college educated people in the surrounding cities of Dover, Lee, Madbury, Newmarket, etc. All of these towns voted heavily for Hillary (not to mention supporting Bernie in the primaries).
