The Sunday shows can’t help themselves

I promise not to do this every Sunday morning — it only seems like I will — but take a look at today’s guest lists for the five major Sunday shows.

* NBC’s “Meet the Press”: Disgraced former House Speaker Newt Gingrich (R-Ga.)

* CBS’s “Face the Nation”: House Speaker John Boehner (R-Ohio)

* ABC’s “This Week”: South Carolina Gov. Nikki Haley (R)

* Fox News’ “Fox News Sunday”: Rep. Ron Paul (R-Texas), Senate Majority Whip Dick Durbin (D-Ill.), Senate Minority Whip Jon Kyl (R-Ariz.) [Update: Mike Huckabee (R) is a late addition to the line-up]

* CNN’s “State of the Union”: Senate Minority Leader Mitch McConnell (R-Ky.), House Budget Committee Chairman Paul Ryan (R-Wis.), former Bush administration officials Dennis Blair and John Negroponte

For those keeping score at home, that’s two Republican presidential candidates, two House Republican leaders, two Senate Republican leaders, one Republican governor, one former Republican governor, two Bush administration officials, and one Democrat.

Liberal media, indeed.

In fairness, it’s worth noting that after these headliner guests, the shows will feature panel discussions, and some of the voices will be center-left. Paul Krugman will be on ABC, E.J. Dionne Jr will be on NBC, and Joe Lockhart will be on CNN.

But (a) this doesn’t make up for the seven-to-one imbalance among officeholders and candidates; and (b) each of the center-left guests will be featured alongside a conservative, presumably to offer the kind of “balance” viewers won’t get with the headline guests.

Rachel Maddow noted the other day, “The Sunday shows are supposedly the apex of political debate — the pulsing, throbbing heart of what’s going on in American politics.”

Right, and week in and week out, this debate is dominated by voices from only one party.

A couple of years ago, Josh Marshall talked about how the Washington establishment is simply “wired” for Republicans. It’s GOP ideas that get attention; it’s GOP talking points that get internalized; it’s GOP voices that get aired.

The Sunday show guest lists help drive the point home nicely.
