Perhaps, but it's quite a stretch to believe Tulsi is some Russian operative. I doubt she'll run a third party as that of a complete waste of time, and it's very easy to argue that a third party run would hurt Trump more than a democrat. her best bet is to hook up with Biden, run as his V.P. and assume he'll never finish his term in office. That is also the best ticket for the democrats, assuming there will be no other entries down the road. Tulsi/Buttigeig would be more radical, not in the radical left sense of the word, just a radical move politically speaking, which is what the country is desperate for regardless of what the "experts" think.
