An early January poll from CNN, taken before the Iowa caucuses, showed Haley just seven percentage points behind Trump. A new CNN poll, taken Jan. 16-19, showed Trump regaining a double-digit lead at 11 percentage points.
The former president now claims half the New Hampshire primary electorate, according to the poll, while Haley holds 39%. Though Trump holds a greater lead now, the poll shows the highest level of support yet for both candidates.
Gov. Ron DeSantis (R-FL) holds 6%. He is below the 10% minimum needed by state party rules to claim delegates in the state.
One in five Republican primary voters in the state are still undecided, and over half are leaning toward Haley. Whether this will be enough to pull off a victory will be seen on Tuesday.
The CNN poll was conducted by the University of New Hampshire Survey Center from Jan. 16-19. The Republican primary section of the poll surveyed 1,210 likely Republican primary voters, with a margin of error plus or minus 2.8 percentage points.
