Joe Biden risks losing a key purple state by flipping off New Hampshire voters in an election that could come down to just a few electoral votes.

The president’s campaign has made a calculated risk that Granite State voters will forget Biden’s snub of refusing to put his name on the primary ballot.

Chances are they won’t forget. New Hampshire has four electoral votes and in a close election losing them could be a major blow to Democrats’ hopes of holding on to the White House.

But Biden has chosen South Carolina over New Hampshire and Iowa by endorsing the Palmetto State primary first in line – rewarding the place that rescued his 2020 campaign.

South Carolina is now the leadoff voting state in the selection process under Democratic National Committee rules, but New Hampshire is ignoring that DNC list, vowing to hold its primary first under its own state law. Iowa Democrats are also working to preserve their early January caucus.

“While the president wishes to participate in the primary, he is obligated as a Democratic candidate for president to comply with the Delegate Selection Rules for the 2024 Democratic National Convention promulgated by the Democratic National Committee,” Biden campaign manager Julie Chavez Rodriguez said in a letter advising New Hampshire officials he won’t be on the ballot.

Baloney. Biden is picking South Carolina over New Hampshire for strictly political reasons and for payback for embarrassing him four years ago.

Biden finished fifth in the New Hampshire primary and wants to punish the state that kicked his butt.

His campaign is likely instead to mount a write-in campaign and finish first that way – the same strategy President Lyndon Johnson used in 1968.

“The reality is that Joe Biden will win the NH FITN (first-in-the-nation) primary in January, win renomination in Chicago and will be re-elected in November. NH voters know and trust Joe Biden that’s why he is leading Trump in NH by double digits,” NH Democratic chair Ray Buckley said in a blustery statement.

The only problem is Johnson dropped out of the race after Democrat Eugene McCarthy finished a closer-than-expected second. So, if Biden doesn’t earn a resounding write-in victory, it could be viewed as a loss.

The move by Robert F. Kennedy Jr. to abandon the Democratic race and run for president as an independent makes it easier for Biden to slide by. But the president could now face Democratic opposition from U.S. Rep. Dean Phillips, who decided Friday to launch a primary challenge. The moderate Minnesota Democrat has argued that Biden is too old to run again and filed papers on Friday to get on the ballot in New Hampshire.

Phillips’s surprise decision could complicate Biden’s plan for a write-in win in the Granite State.

“I think it’s a mistake that he’s not putting his name on the ballot,” New Hampshire Secretary of State David Scanlan said.

Consider that a warning.
