Commentary:

So you rarely hear this word except during election time in the United States. I like it because it has the sound “guber” in it, which sounds kinda fun. Goooober. One word which is very similar that you hear far more often is presidential.  So if you can use the word gubernatorial in any place where you might use presidential, assuming you’re talking about a governor instead of a president.
