Roughly 1/3rd voted for him, 1/3rd voted for Harris, and 1/3 of eligible voters didn’t show up at all.
And he didn’t run on invading Greenland or Venezuela. He famously ran on “America First,” and constantly shit on foreign conflicts / nation building. So this literally the exact opposite of what his voters signed up for… which is why some of the big MAGA people are super pissed right now.
