I thought his best line was...
"You need to re-elect me because we need 4 more years of Laura."
Every time he mentioned the UN, the whole crowd booed LOUDLY! It seemed like he was surprised but amused.
He's used the 4-more-years-of-Laura remark for about a month now and he always gets great applause for it.
Nice pictures --- and I'm not surprises about the UN booing.
