What are they really saying ?

Question

when their speechs contain nothing but attacks?

Answer 1

I totally agree. I had to turn the tv off when Palin started to rehash all the hatred of Obama and all the changes needed in Washington. Does she, McCain, Romney, and Giuliani not know how to pronounce George W. Bush? They did not introduce or detail any of their policies, they just kept crowing about how much a hero McCain still is and how much experience being the mayor of a town under 10,000 brings you. McCain was a hero, but we all know that past event. Where's the forward looking?  

Answer 2

it's expression that implies they have negative feelings about something or someone. Negative feeling could be hate, envoy, anger, etc.
