At this point, I think he is likely quite a lot less dangerous than Presidents like Kennedy, Carter, Clinton and Obama.
I could do an essay on each one that shows how they were extremely dangerous to the nation, but I would like to think most conservatives are already informed about such things.
But then again, look how many there are that don't recognize how dangerous Hillary is.
And the obvious difference that you fail to discern is.....
he is much more dangerous than all of those Democrats you mentioned...
because his cheetoh stain will spread across and destroy the Republican Party, and along with it....the conservative movement...which is, by the way, the only movement that has (or had) a chance of saving this nation from sure-fire collapse.
By that means alone Trump is much more dangerous to the American right......thereby handing future victories, possibly all future victories, to the radical American left.
