Of course we can. People disagreeing with you doesn't mean they don't exist.
These are the Senate seats in play this cycle [1]. How many of those do you think would be flipped based on any foreign policy item?
If you're on this thread you pay attention to foreign policy. The notion that someone doesn't–not isn't informed, but literally doesn't to any degree–is almost more foreign than the strangest countries we read about. But the truth is most Americans have never ranked any foreign policy item as being in their top three issues since the Vietnam War.
We could change it if we wanted to. We don't because it's not personally pertinent or worse, it's boring. (And, I'd argue, because a lot of foreign-policy oriented activists are preaching for the choir versus trying to actually effect change.)
