Well, not to put words in your mouth, but I believe you mean you could NOT care less how a President speaks.
Be that as it may, I would respond by saying, "Good for you". But, as a political reality, the rest of the country - the people who actually elect Presidents - do seem to care about a Presidents ability to effectively communicate.
"He speaks well but he lies everytime he opens his mouth. Much rather someone who speaks the truth and walks the walk. I think most Americans would agree."
Bill Clinton was impeached for lying - for lying. And yet, he enjoyed an approval rating in excess of 60% when he left office. Most polling I've seen says that he would have easily won a third term, if he'd been allowed to run.
Bill Clinton was the poster-child for slick mendacious politicians. And yet, he's still incredibly popular. Voters like politicians who speak well. They tend to not like voter's who don't speak well. It's just a political reality.
Are you saying that most here believe in style over substance? I pray that you are wrong.
