President Obama blew one of the most iconic signature lines in the history of music Thursday night ... as he paid homage to Aretha Franklin at The White House.
Obama touted Aretha's iconic song "RESPECT" by calling it "a rallying cry for African-Americans, women, and then everyone who felt marginalized."
Problem is ... he spelled R-E-S-P-E-C-T wrong.
Whether you want to hear it or not, Obama got a pass that George W -- the Bush famous for malaprops -- would never have gotten.
By the way ... after the event -- which honored "women of soul" ... we asked Aretha if there will ever be another A-R-E-T-H-A.
