Yes, that's the Republicans.
The latest act of stupidity was an open later to Iran essentially saying it doesn't matter what kind of nuclear agreement you come up with we're going to win the next election and undo it anyway.
The letter was signed by 47 GOP senators supposedly to explain to the Iranians how the US Constitution works.
The Iranian response made it clear they understood the US Constitution better than the Republican senators and also understood International Law which the GOP didn't even seem to take into account.
Newspapers in the US and US Allies blasted the GOP action but in the arrogance of the Right Wing, they don't seem to care and neither do their trailer park base.
Like John Cleese says, they're just too fucking stupid to realize how stupid they are.
As for the Republican base, "hey, we're "mericans' and can do whatever we want" is their credo. Each and every one is a firm believer in American Exceptionalism. They're just opposed to everything that might make the country exceptional such as equal protection under the law and the separation of church and state.
Yes, I'm now no longer sticking by my "no foul language" rule. Screw it. I've fucking had it up to here with Right Wing lies, ignorance, backfire effect and just plain stupidity.
