Agreed. The one thing I do hold against TR is his hubris in 1912 divided the Republican vote and helped put that megalomaniacal racist ba$tard into office. Taft may have been a tool of the Ohio machine wing of the party, but he wasn’t Wilson.
Teddy Roosevelt had stood in for Eleanor's deceased father at her wedding to dashing young Franklin Roosevelt in 1905.
Unlike Teddy's Oyster Bay Roosevelts, Franklin's Hyde Park Roosevelt family were staunch Democrats and in 1912 Franklin became an original Wilson supporter.
That alienated some Roosevelts from each other, but not Bull Moose Teddy, I think because in fact Teddy's & Franklin's actual politics were not very far apart.
Teddy loved that Franklin opposed Democrat Tammany Hall.
The upshot was that young Franklin immediately became Number Two in Wilson's Navy Department, and learned much from Wilson's First World War mistakes.
My guess is that seeing young Franklin in charge of old Teddy's Big Stick navy must have provided him significant satisfaction, more than compensating for Teddy's disappointment at losing in 1912.
