Well, I'm certainly glad to see that Wilson has no votes. Seriously, **** that guy. But his wife Edith deserves tremendous praise and credit for her efforts on the 19th amendment. It's a shame we couldn't have her instead of him the whole time.
In terms of presidents, as opposed to their congresses, really standing out and making a difference, the best probably has to go to FDR. In terms of having a vision and making it come true, and that vision being such a game changer and transforming this nation into its modern shape and doing so much good for so many Americans... it's hard to top FDR. Of course, one person having that much power is somewhat contrary to the vision of divided power in this country, so there's definitely a double edge to that sword.
Johnson should get more credit than he does for his strong support for civil rights. Carter should get more credit than he does for his anti war stances. And I'm personally a fan of Jackson and his populism and stances against the financial elite. Taft likewise should get more credit for his opposition to the financial elite. He did more trust busting than Teddy.
I'm honestly baffled at why people like Kennedy so much. What did he do that was so worthy of admiration? I know people liked him because of his youth and charisma, but the only actual things I know of that he did were getting us into Vietnam and not starting a war over the Cuban Missile Crisis. The latter is good, but hardly cause for all the praise he gets. Oh, and he was really really unfaithful to his wife.
