2.) I don't think Obama is the most liberal President in US history, but of course, it all depends on what you mean by "liberal." Since you inexplicably capitalized it, I suspect you mean it as an invective, not a reasoned analysis of his ideology and political motivators. Carter, LBJ, Woodrow Wilson, Theodore Roosevelt, Abraham Lincoln, and possibly FDR were more liberal. From a policy perspective, Nixon was much more "liberal" than most people remember. The Watergate scandal overshadows everything he did as President.
This is delusional. Sorry brother but this is so far from reality.
