The Human Rights Campaign is launching a spending push in six key states to rally “equality voters” — and warns that many still need to be persuaded to vote for Biden.

And after crunching the numbers, the organization sees warning signs in the form of soft support for Biden in the 2024 electorate.

HRC estimates that this year there will be 75 million “equality voters” — who vote based on support for LGBTQ rights — up from 62 million in 2020 and 52 million in 2016. But the group says one-third of them aren’t a lock for Biden. In the six key swing states, hundreds of thousands are “at risk of not voting,” and another group of hundreds of thousands of voters are what HRC refers to as “double doubters” who will likely defect to a third party, according to data HRC shared with NBC News.
