DNC and RNC covered by both Sirius and XM

Both Sirius and XM will be providing comprehensive live coverage of the Democratic and Republican National Conventions, starting on August 25th for the DNC and September 1st for the RNC.

Sirius will debut "Sirius Convention Radio" with live, uninterrupted coverage of every speech from the convention podium, and replays of each day's highlights. The dedicated channel (oddly, I can't find its channel number) will also air information on convention agendas, schedules, events, and meetings, as well as reflections of past conventions with DNC and RNC members.

Real-time Spanish-language translations of every speech will also be airing on "Sirius Convention Radio En Espanol."

In addition to the Sirius Convention Radio channels, Sirius will also present live broadcasts from the conventions on its talk channels: Sirius Indie Talk (ch 110), Sirius Left (ch 146), Sirius OutQ (ch 109) and Sirius Patriot (ch 144).

Sirius hosts Ron Silver, Michelangelo Signorile, Mark Thompson and Andrew Wilkow will broadcast their shows live from the conventions while hosts Alex Bennett, Lynn Samuels, and Mike Church will be on air with special convention programming from the Sirius studios.

Meanwhile, XM Satellite Radio will also be airing commercial-free coverage of the Republican and Democratic conventions on XM's presidential election news channel POTUS '08.

POTUS '08 (ch 130) will have complete, gavel-to-gavel coverage of the conventions, plus news and interviews with party insiders, reporters, pundits, protesters, and bloggers.

POTUS '08 anchors Joe Mathieu, Rebecca Roberts, and Scott Walterman will report from the Democratic convention in Denver. Anchors Tim Farley, Mathieu, and Walterman will be at the Republican convention in St. Paul. During each convention, anchor Adrienne Mitchell will report on the opposing party from Washington, D.C.

Replays the day's highlights will air during the overnight hours.

Next week, Oprah & Friends (ch 156) host Gayle King and The Power (ch 169)'s Joe Madison will bring their morning programs to the convention hall in Denver, and the Human Rights Campaign's weekly XM show "The Agenda with Joe Solmonese" will be live from the convention floor on XM Live (ch 120).

XM talk radio channels America Right (ch 166), America Left (ch 167), and TalkRadio (ch 165) will provide a steady stream of no-holds-barred commentary through the conventions.

The Democratic convention will take place August 25-27 at Denver's Pepsi Center and August 28 at INVESCO Field, where Sen. Barack Obama will deliver his acceptance speech as the party's nominee.

The Republican convention will take place September 1-4 in St. Paul, Minnesota at the Xcel Energy Center, where Sen. John McCain will accept the GOP nomination.
