Typically when a presidential candidate is putting up mega-landslide margins in the early primary states, it’s clear to all that he’s on his way to becoming his party’s nominee.

Nothing is typical in American politics anymore.

Ask the average Republican voter (or average Republican presidential frontrunner) which Democrat will top the ballot this fall and you’ll be surprised at how few, even now, answer “Joe Biden.” Some assume the president can’t conceivably last another eight months, believing that he’s been living on borrowed time for years. But for many, it’s not the Grim Reaper blocking his path to a second term. It’s Michelle Obama.
