I have as much right to discuss politics in America as you do! And I likely have more good sense than you, because democracy has come a long way since 1786. It was WW2 that gave Europe the opportunity to redefine it in Progressive Terms and call it Social Democracy.
Progressive political thinking had a brief life in the first half of the 20th century with Teddy Roosevelt who created the Progressive Party to support his bid for the presidential election of 2013. He lost that vote - and what should have become the Democrat Party was lost in history as well.
What remains is the Congressional Progressive Caucus in the HofR, with their Progressive Promise.
But, you are not to worry - the CPC has only a minority representation in Congress. And only one member from the Senate - a guy by the name of Bernie Sanders.
Which should show all of us how very far we have to go towards reinventing America ...
