This makes no sense to me. Tom Cotton is one of the most fiscally conservative members of the Republican Caucus, a $5k donation by a billionaire hedge fund manager isn't going to sway his opinion on progressive tax reform. He voted to cut taxes in 2017 and has voted consistently against bills that either closely or somewhat align with what Dalio is proposing. Dalio clearly benefits financially from conservative fiscal policy, which senators like Cotton support. It's a big stretch to argue that Dalio might be trying to sway Cotton on his fiscal policy while also benefiting financially from it.
