Ok, first of all, both of the links you provided show the same info related to fans - which puts the % of NASCAR fans that identify as White, at around 80%.  So, I stand by my original statement which was that the "overwhelming majority of its drivers and fans are white."

Neither of the links you provided say anything about minority drivers.  But, using the interwebs, I found that NASCAR has only had 7 black drivers compete at the "top" level.  Ever.  And the stats for women are even worse.  So unless there is a massive Hispanic or other minority population of NASCAR drivers that I cant find the stats on, I will again stand by my original statement.

And DirecTV is pretty good about offering refunds for the NFL Ticket.  I had it a few years back and forgot about it until the 3rd or 4th game of the season (when I got my bill and noticed it was substantially higher).  Called them up and they refunded me nice and easy.  I wouldnt take it as a sign ATT or DirecTV agrees with Trump.
