NCAA athletes aren't a specific group? Yes, I'm aware that they play different sports and are different races. They are still a unique group, as seen by the fact that one governing body makes a rule that applies to all of them collectively. So yes, they are a specific group.
And ftr, people like me have done very well personally and financially under 4 presidents(caught the tail end of Clinton), and will continue to do so regardless of whatever schlep, D or R, the voters select. I don't like any of them and never have. What I dislike even more though is the incessant whining that I've had to endure for the past 45 months. When it was non-stop foot-stomping about the previous guy, trust me I conveyed the same message. You just didn't see that because sports were almost entirely(gasp) devoid of politics.
To your last point, yes they may not be telling anyone who to vote for. But all this talk about getting out to vote is absolutely a loaded message of "make a change" or basically "vote for Biden", which is fine by me. If your life is somehow that dependent on a guy who's been a part of the system for 47 years and yet claims it's apparently worse now than ever but has the magic fix, then you're hopeless anyway and too dumb to have any impact on my life.
