R. W. Johnson - Rotsa ruck on that. The 'left wingers' (they're left compared to what) probably represent the average (working, that is) American Citizen to a substantial degree while the 'righties talk show artists' are generally funded by large corporation where, guess who, the affulant CEO's make the decisions. They know on which side of the bread is the butter. Say it isn't so. I suspect, in most instances, the lefties are left only because they are left (more central) then the 'far righties'. McCain cliams he can solve our problems, but as a confidant of the President, where has he and his advice been the past 8 years. The Democrates are in the majority in Congress but that majority in meaningless unless it is great enough (60 votes) to override a Veto. That they don't have. Stay tuned.

Some Republican Rock (and Metal, Punk, New Wave):
Lynyrd Skynyrd
ZZ Top
Foghat
Kid Rock
Alice Cooper
Gene Simmons
Bob Seger
Danny Elfman (Oingo Boingo, Wrote the Simpsons Theme)
Neil Peart of Rush
Meat Loaf
C.C. Deville (Poison)
James Hetfield (Metallica)

Styx, SmashMouth among others performed for the RNC

As other mentioned County (the working man's music) is as Republican as rock appears to be liberal.

For example these are all part of this years RNC:
Trace Atkins
Gretchen Wilson
John Rich
Montgomery Gentry
Julianne Hough (the dancing with the stars girl)

My guess is you can Cat Scratch Barracuda from the Republican list.
