Randi’s taking a much-deserved day off today, and I’m thrilled and grateful that she’s once again asked me to fill in for her!  I hope you’ll join in.  I’ve got some great guests lined up, but made sure to leave lots of time for your calls at 866-87-RANDI (866-877-2634).

You can listen live through any of Randi’s affiliates, and I’ll have the video stream going too.

Of course, the big news continues to be the biggest environmental disaster in our history. Today is Day 60 of the Gulf geyser. Although it’s been a busy week of dealing with the disaster, the estimates of the amount of oil spewing from the blown out well keep skyrocketing.

On Tuesday, President Obama spoke to the nation from the Oval Office. On Wednesday he met with BP executives. And yesterday, BP CEO Tony Hayward was in the hot seat in front of the House Energy & Commerce Subcommittee on Oversight and Investigations.  He took a pretty good beating, and got one apology.  Seriously.

We’ll talk about all of that today.

We’ll visit with some great guests:

Actor and Huffington Post contributor Steven Weber will join in during the first hour.

Brad Friedman, who does some amazing reporting at The Brad Blog, will fill us on on what happened last night in South Carolina, as the Democratic Party Executive Committee met to determine the fate of the Senate primary in which unemployed Alvin Greene won. It’s an odd case, and what happened last night is even stranger!

I’ll chat with WSJ columnist, author of numerous books (including The Wrecking Crew and What’s the Matter With Kansas?) Thomas Frank in the second hour. (To read his latest WSJ column, “Britain Cries Foul Over BP,” click here and then click on the first search result.)

And in hour three, Rolling Stone magazine’s Tim Dickinson will join us to talk about his explosive new piece, “The Spill, The Scandal, and the President.”

Welcome to Randi’s listeners who are visiting Radio or Not for the first time.  I host my own show here Monday through Thursday evenings from 6-8 pm ET.  I hope you’ll come back!
