Booker likely will be hard to beat in the Primary (esp in a crowded field)

[Thunderbird is the word]

In some ways Booker (at least from a left-wing perspective) would be even worse then Hillary. He'd probably campaign openly and unapologetically on support for TPP like deals and would essentially represent the complete realignment of politics where the Democrats would become a fiscally conservative and socially liberal elite party and Republicans a right-wing populist one.
