Oh he's got policies and they are popular. Some of them are totally nuts but the core of it is "American industry first" - his domestic and foreign record reflect this. He's not big on war, which is a relief, and is big on protectionism (i.e. restrict trade to help local economy). He's the party of tax breaks for business & favourable trade & strong borders & Christian nationalism & not starting beef internationally
Overall, despite all the drama and racism, at least he's not a warmonger (like pretty much everyone else). He just did one little local coup/riot. "Boys will be boys" as they say XD hahaha
