I don't know why, but it just does to me.

Harold Ickes

Harry Hopkins

Felix Frankfurter

Henry Wallace

Cordell Hull

Frances Perkins

Rexford Tugwell

It's almost like the TCOT naming convention but, for 20th century liberals.

The only one with a similar sounding name that stands out is Wendell Wilkie, who obviously wasn't a New Dealer.

Edit: Related to that, when Howie Hawkins ran for president four years ago, my first thought was: "I thought that guy was dead," because I was thinking of Harry Hopkins. The last guy out there with a New Dealer-ass name.
