Special to our right-wing friends: Turn on MSNBC at 7:00 pm MST tomorrow and tell us what you think.

Yup, it’s the debut of “The Rachel Maddow Show,” featuring Air America’s Rachel Maddow. You may have seen her guest-hosting “Countdown” or in her role as an MSNBC political commentator.

Here’s a sample, from last Friday, of Rachel’s unique voice as she comments on the Republican National Convention. “Let’s call lies, lies” Maddow says.

Also, don’t forget, Barack Obama is going to be on Keith Olbermann’s show Monday night.

UPDATE: In an act of supreme cowardice, MSNBC has caved in to right-wing demands that Keith Olbermann and Chris Matthews not be allowed to continue anchoring their election coverage.

UPDATE: In her third night on the air, Rachel Maddow scored an exclusive on John McCain. Matt Yglesias:

[T]his is why Rachel Maddow matters. As of last week, had a liberal journalist like Ari Berman broken a news story like this it would have been published on The Nation, picked up in some blogs, and then it would have died. Now, it’s on television.
