Welfare use in US

I have the elections on my mind, as I'm sure most of you do too.  I am constantly amazed by groups of people who consistently vote against their own best interest and nothing highlights this better than healthcare.  This article came out in the NY Times in February and perhaps everyone has already seen it, but I wanted to post it because the image of this map keeps resurfacing for me.  It's a powerful visual, especially when compared to the red and blue maps we've all been seeing during election season.  It saddens me that some of the people who are in greatest need of government services are those who vote for a president who vows to deeply cut the programs that deliver these services.
