The use of curse words doesn't bother me one bit. Calling other countries **** holes didn't bother me at all. In fact I haven't commented on it as of now. I really don't care. I don't care if Obama used cursed words or not. I doubt that Trump or any other president can ever overcome LBJ in the use of foul language. No big deal. What I don't like is this, well so and so president used them, so its okay for my president to do the same.
Fact is using curse words is very un-presidential. LBJ was very adept not to use them when speaking to the American People or when recording devices were around. But he would cuss out senators, representatives, members of his own administration. Trump's approval or non-approval rating isn't suffering because of his policies or stances on the issues. It's below 40% because of his persona, his very un-presidential behavior, his temper tantrums via twitter. People as a whole don't like that. That is outside of his avid supporters.
The American people are pretty split evenly on his policies, a list of 16 issues showed on seven of them, Americans approved vs. nine in which they opposed Trump policies and stances. That should translate into roughly a 50% job approval, favorable view of Trump. It doesn't. His persona, his uncouthness, his unbecoming behavior, words, actions isn't what people look in a president.
How this will translate out come the midterms later this year, time will tell. But I would wager it will be Trump's persona, his very unpresidential behavior that will give the democrats congress. Not necessarily Trump policies.
