Not long ago Samuel L. Jackson was telling America to “wake the f*ck up” and vote for Obama.

Via Daily Mail:

Samuel L. Jackson has blasted Barack Obama for ‘promoting mediocrity’ in the United States by ‘dumbing down’ the way he speaks to ordinary Americans.

In an expletive-filled tirade about – of all things – grammar, Jackson told the President to ‘be f*****g presidential.’

The Holywood legend, who publicly backed Obama in 2008 and 2012, questioned why the Harvard-educated former law professor chooses to drop the letter ‘g’ from the end of his words.

In an astonishing rant, Jackson, 64, said that the President was trying too hard to ‘relate’ to normal people instead of being true to who he really is.
