When I look at the left's response to the Trump campaign it reminds me of the Popular Front period in the 1930's. At that time, the various diverse elements of the American and European Left  put aside their doctrinal differences and joined forces to oppose the spread of fascism. It troubles me that Milbank doesn't see this.

The results then were ambivalent, of course--especially given the 1939 non-aggression pact between Stalin and Hitler--but  now  there exists  a similar imperative to unite in order to resist the rise of something that looks very much like fascism in the form of Trump. 

The problem Chomsky identities is that the contemporary Democratic Party has moved so far to the right while the Greens have yet to build a viable national party. Stein's critique of Clinton's associations with the corporatist security state has considerable weight and accuracy, but the Greens have yet to build the national, regional and local organization that would give that critique relevance
