Were they Republican or cross party voters?
Anyone who was registered as or switched their party to Republican back in October, or before and Independents can vote for the Republican Primary presidential candidate. People currently registered as democrats can't vote in the New Hampshire, Republican Primary.
A lot of democrats in New Hampshire switched, since the democrat party chose not to count the New Hampshire, democrat primary. biden chose not to be on the ballot, but his lame supporters are asking he be written in.
