It's debate night tonight, with both the Republican and Democratic candidates going head-to-head in back-to-back debates in Manchester, New Hampshire.
It's the first debate with the primary season underway so expect to see a new post-Iowa dynamic. What lines will Hillary Clinton use against Barack Obama as her New Hampshire poll lead shrinks or maybe goes into reverse? Will John Edwards, as he did yesterday, continue to compare himself to Seabiscuit. Or, also yesterday, draw inspiration from Blair-on-Diana line to call himself the "people's candidate".
Expect appeals to change - the word Obama has made every candidate's favourite - on the Republican side too. Mike Huckabee is polling a clear third place in New Hampshire behind John McCain and Mitt Romney (12% to McCain's 32% and Romney's 30% in the latest Reuters/C-Span/Zogby poll) but his defeat of the high-spending Romney will force the former Massachusetts governor on the defence. How will he re-invigorate his message?
Finally, this is the ABC/Facebook debate. While it is unlikely Clinton will poke Obama, or Romney will unleash his vampires on McCain (but wouldn't that be fun), I'll be keeping a watch on any sign of social networking on the stage. And, as always, add your comments below.
The Republican debate begins at 7pm ET (midnight GMT) and is followed by the Democrats at 9pm ET (2am GMT). Both last 90 minutes.
