Chris Matthews blames the Berlin Sun for ruining Obama's speech:
MSNBC host and Obama sycophant Chris Matthews blamed the sun for spoiling the president’s speech in Berlin today
“I think a lot of the problem he had today was the late afternoon sun in Berlin ruined his use of the teleprompter and so his usual dramatic windup was ruined,” Matthews said immediately after the speech. “I think he was really struggling with the text there.”
Speaking behind a glass bulletproof shield, Obama appeared to be using the text of the speech rather than reading off of teleprompters.
