A grassroots organization in the US, "Vote Ceasefire," is urging Democrat voters in New Hampshire to write "ceasefire" instead of Joe Biden on their primary ballots. The campaign seeks to put pressure on the government to restrain Israel in its war on Hamas in Gaza. Pictures posted on Instagram by "Vote Ceasefire" show voters holding up their ballots with "Ceasefire" written on them. The campaign aims to highlight the push for an end to Israel's military offensive in Gaza, which began following a Hamas attack on Israel on October 7. So far, more than 21,000 write-in votes in the New Hampshire Democrat primary remain to be sorted.

Joe Biden was not on the ballot in New Hampshire after the Democratic National Committee decided to make South Carolina the first voting state. However, New Hampshire decided to proceed with its own contest, leading Biden's campaign to swear off the state's primary. In response, his allies launched a write-in campaign. "Vote Ceasefire" is using a similar tactic to demand a ceasefire in the Israel-Hamas conflict. The campaign has the support of some prominent state politicians and is expecting a larger-than-normal number of write-in votes.
