4 exit poll numbers that explain Trump’s New Hampshire primary win

Former President Donald Trump’s dominance among the GOP’s base voters fueled his victory in the New Hampshire primary Tuesday, according to NBC News exit poll results.

While former U.N. Ambassador Nikki Haley managed to win independent, or “undeclared,” voters, Trump’s wide margins among self-identified Republican and conservative voters were too vast to overcome. Just like last week’s Iowa caucuses, the New Hampshire primary also underscored how Trump’s ardent supporters have taken over the Republican base.

Here are four numbers from the NBC News exit poll that help explain Trump’s win:

1. Trump’s GOP margin

Three in 4 New Hampshire GOP primary voters who self-identified as Republicans supported Trump, and they comprised a majority of the electorate (51%). Haley won 60% of voters who described themselves as independent, but by a 22-point margin compared to Trump’s 49-point advantage among Republicans.

2. Conservatives dominated the electorate

Self-described conservatives dominated the primary electorate, with 66% of voters describing themselves as such. Trump won 70% of them. Haley won 73% of self-described moderates, besting Trump by roughly 3 to 1, but they were a smaller share of the electorate (28%).

3. The new, pro-Trump GOP base

In the Trump years, the GOP has found success among non-college-educated voters, and Trump handily won that group Tuesday night. Voters without college degrees were a majority of the electorate (52%).

Among voters without college degrees, Trump won 66%, while only 32% voted for Haley. Trump’s performance among those voters was also up 24 percentage points compared to 2016, when he won 42% of them.

Although they made up smaller shares of the electorate, Trump also won among other groups
