Every vote RFK2 takes from Biden makes it harder for the Dems to steal the election. We should expect that RFK2 will have more progressive policies on things like student loan reform, etc. Progressives disillusioned with Biden are also very likely to support needed electoral reforms, like ending proprietary voting machines, etc. The ruling class is actually neither conservative nor progressive. The more people who see the truth of the Uniparty, the faster real reforms will come.
Interesting point.
