Correlation between car color and political leanings?

Ok, this is my first question, and it’s asinine. I started to notice this trend many years ago, and was convinced it was confirmation bias. Then it started to become absurd. Note: The following is my observation, applies to Massachusetts, is in no way intended to offend, and may be just wrong.

Here it is: It appears to me that a white car/truck owners are much more likely to be socially and fiscally conservative and Christian.

(Of course there are exceptions. I wish, however, that there was some way to determine if there was statistically anything to this.)
Has anyone noticed this?
