Welcome to msnbc's live blog of the first presidential debate, featuring Krystal Ball, co-host of msnbc's The Cycle; Joy-Ann Reid, managing editor of NBC's TheGrio.com and an msnbc contributor; and Richard Wolffe, executive editor of msnbc.com.
They'll be keeping the candidates honest, assessing who's having the better of the exchanges, and judging whether all those "zingers" that Mitt Romney promised us are hitting their mark. And we want to hear from you too, so send us your comments and we'll post a selection of them on the live blog.
We'll kick things off at 9pm EST sharp. See you then!
