After a record-setting near 30-point win in the Iowa caucus, former President Donald Trump has headed to New Hampshire to do what no candidate in a competitive Republican primary has ever done—win both Iowa and New Hampshire.

Incumbent presidents sweep the primaries all the time — when they don’t, or if the primaries are close, they usually lose — but not when the nomination is contested without an incumbent president running. …

[I]f Trump sweeps the early states of Iowa, New Hampshire, and South Carolina — Trump has led 100 percent of the polls taken in South Carolina this cycle — 2024 has the makings of being one of the greatest blowouts in not just GOP primary history, but all competitive presidential primaries.

[Trump is an incumbent in this cycle, if not literally then at least symbolically. There is a very real chance now of Trump running the table; Iowa may have been the biggest obstacle to that, and it turned into a Trump landslide. A few caucus states may deprive him of a shutout (maybe Minnesota?), but unless either Haley or DeSantis win states before or on Super Tuesday, a shutout may be what’s coming. — Ed]
