Tonight is arguably the biggest night of the Republican National Convention, as it will be vice presidential candidate Sarah Palin's first national campaign speech. Politico has five things to watch for, including how Palin will have to emphasize why she's experienced. Her aide said, "She will speak as a governor, a former mayor and someone with both hands on the steering wheel of America's energy economy. She will detail her record of shaking up the status quo in Alaska and standing up to entrenched interests to put the government back on the side of the people."

Hilariously, two Republican pundits were caught on live mic "bemoaning" the Palin pick. Per The Caucus, Peggy Noonan doesn't think she's the most qualified, "No. I think they went for the — excuse me — political (expletive) about narratives. … Every time the Republicans do that, because that’s not where they live and that’s not what they’re good at, they blow it.” In another vein, the Washington Post has an article on the McCain camp's war against the media.

Also in prime time will be former mayor Rudy Giuliani, so expect lots of 9/11, America's darkest day, etc. Other speakers tonight are others who tried to win the Republican nomination: former Massachusetts Gov. Mitt Romney and former Arkansas Gov. Mike Huckabee.
