It seems you're asking for information on a billionaire family that is allegedly funding both anti-Israel groups and certain Democrats in battleground states. However, without specific names or more context, it isn't possible to provide accurate information. There are many billionaire families involved in different political areas globally, and their motivations can range from personal beliefs to business interests. If you can provide more specifics, I'd be more than happy to help research this further for you.
