With a $750,000 infusion from a California group, a political committee backing a proposed constitutional amendment on felons’ rights has continued building a stockpile of cash for the November campaign.

The committee Floridians for a Fair Democracy raised slightly more than $1.25 million from Aug. 11 through Thursday and had about $8.46 million in cash on hand, a new finance report shows.

The proposed constitutional amendment, which will appear on the November ballot as Amendment 4, would automatically restore voting rights for all nonviolent felons who have served their sentences, completed parole or probation and paid restitution.

Felons convicted of murder and sexual offenses would not be eligible.

The proposal, which would require approval from 60 percent of voters to pass, comes after years of political and legal fights about restoring the rights of felons who have served their sentences.

Of the money raised recently, the largest chunk, $750,000, came from the California-based Open Philanthropy Action Fund. The fund is linked to the Open Philanthropy Project, which is mainly financed by that organization’s president, Cari Tuna, and her husband, Dustin Moskovitz, a co-founder of Facebook and Asana, according to the organization’s website.
