This is like when Trumpies said they'd boycott Hamilton. So, just like me "boycotting" NASCAR, then.
Okay, I'm sure there are actually plenty of Trump voters who go to Starbucks. And probably, in Butthole Nebraska it's pretty hard to find a place that sells coffee that ISN'T Starbucks. (Okay, I guess McDonalds, if you want that special sheen of meat juice floating on top. But if you think McDonald's isn't hiring immigrants then explain to me why they've set up their registers so you can run them without speaking a word of English.)
Anyway, let's just say Howard Schultz is probably not quaking in his boots.
