Sarah Palin's Big Speech Tonight!

Tonight is the biggest night in Sarah Palin’s political career.

She’ll be speaking around 10:30 p.m.

In the speech, Palin is likely to emphasize her areas of policy expertise — particularly energy and political reform — rather than focusing on her biography or gender. reports MSNBC.

An initial version of the address, which speechwriter Matthew Scully started crafting a week ago for an unnamed male vice-presidential pick, included plenty of attacks aimed at Democratic nominee Barack Obama along with ample praise for McCain, aides said. But they said Palin’s speech will focus more on substantive matters.
