From MSNBC:

SIMI VALLEY, Calif. – Ten Republicans, one stage, 90 minutes — just enough time for Rudy Giuliani, John McCain or Mitt Romney to make a major gaffe as underdog rivals scramble for relevance during the first Republican presidential debate Thursday.

The three heavyweights were expected to boast of their own accomplishments and outline their visions for the future, mainly playing it safe as they sought to start distinguishing themselves from one another eight months before the first Republican primary votes are cast.

It will be 8pm eastern on MSNBC.

Also, I will have the complete 90 minute debate video, unedited, up here in a day or two following.

Update:

The entire 90 minute debate can be viewed here.
