Nothing will happen the Union will be as strong as its always been
This is just bluster from people who cant accept that there guy (who the huge majority of republicans hated) lost
Bottom line is anything the president wants will be voted down by congress anything the republican congress wants will be either voted down by the democratic held senate or the presidents veto pen
America will not turn communist the sky wont fall it will just be business as usual IE nothing will get done
In the word of the Hitchhikers guide to the galaxy DONT PANIC!
