Why was Rhode Island so close?

Been a lurker here for a while. Thought I'd comment (although it's mostly been answered)!
RI has similar demographics to Massachusetts but with more Italians, Catholics (more socially conservative) and fewer wealthy areas (meaning it was more receptive of Trump's economic populism). Extremely Italian mid-size middle/working class towns like Johnston and West Warwick managed to vote for Trump after voting for Obama by huge margins because of this. Then there's the WASP factor (White anglo-saxon protestant, think ME-02 or eastern Connecticut) that voted for Trump in huge margins, that you don't see too much in Massachusetts but is common in western and southern Rhode Island.
These differences are also why RI voted for Bernie in the primary while Mass voted for Hillary.
