Can Trump hold his disparate coalition together?

Decades ago, conservatives told a joke that went like this: If members of FDR’s New Deal coalition ever met in one place, a fistfight would surely break out.

After all, what did a Rust Belt union worker have in common with a San Francisco gay rights activist? Or a Northern liberal with a Southern segregationist? And yet, that unwieldy coalition held together for decades.

Today, it’s MAGA that finds itself as the big-tent coalition full of internal contradictions. The question is, how long can it last?
