Final thoughts: Somewhat conservatives are giving Trump critical support
As much as Trump has rewritten Republican politics, there's a long-standing pattern to winning GOP primary races: the candidate who wins the "somewhat conservative" bloc of voters usually garners the nomination — including Trump in 2016. Here in 2024, the difference between victory and defeat for Trump in New Hampshire was his hold on this group of voters. He carried them 60 percent to Haley's 38 percent, and they made up a plurality of the electorate (41 percent), based on the exit poll. This comes on the heels of his 47 percent take among somewhat conservatives in the Iowa caucuses, ahead of Haley's 25 percent, per the Iowa entrance poll. Although Trump's strongest group is now the very conservative wing of the GOP, which was Ted Cruz's base back in the 2016 Republican primary, Trump's ability to still handily carry the somewhat conservative set has enabled him to comfortably take hold of this nomination contest.
