Some people say that this country started left with FDR and his many UNCONSTITUTIONAL programs like SS but it actually happened during the administration of Woodrow Wilson. During his 8 years we got the Federal Reserve, the income tax, senators elected by popular vote, criminalization of drugs AND Prohibition (the last two were convenient excuses to expand government power).
I refreshed my memory by looking up his bio. League of nations, Treaty of Versailles in addition to what you mentioned. That guy was just full of terrible ideas.
Another tidbit on Wilson.
Presidential Election Results (1912)
DEMOCRAT (Wilson) 435 electoral votes 6,286,214 popular votes
PROGRESSIVE (Roosevelt) 88 electoral votes 4,126,020 popular votes
REPUBLICAN (Taft) 8 electoral votes 3,483,922 popular votes
Because of the voting split in the Republican Party, not only was Woodrow Wilson able to win the Presidency, but the Democrats gained control of both houses in Congress.
Close friends and advisor to Wilson, Col. E.M. House (founder of the Council on Foreign Relations) hand picked the first board members of the Federal Reserve Board.
