Trump was pandering, but not to Latinos. He was baiting people into virtue-signaling behavior that annoys his base, which largely thinks that this is a dumb thing to get offended by, and finds the ensuing "of course it's offensive -- everyone knows that!" reaction especially grating. Trump knows what he's doing. I wouldn't even put these two in the same category of pandering.
I also agree that Jeb is probably depressingly proud of his guacamole recipe.
This.
Trump also got in a plug about Trump Tower. He's the king of "brand messaging". Perhaps this is how he's pulled off what he's done so far.
