Republican Senator Ben Sasse is very impressive but may lack the common touch & be a too polarizing figure within the GOP to win their nomination.

The US voters, especially the more progressive, may finally be becoming disenchanted with political dynasties & billionaire candidates.  This may not augur well for the chances of yet another comparatively young & unseasoned Kennedy.

In any case, isn't it rather too soon to speculate about the 2020 Presidential election?  Many now unpredictable events and developments will shape that campaign will they not?
