Rock and Roll Hall of Fame expert Charles Crossley, Jr. offered up his analysis of the 2010 nominees over on his message board.

So, let's break up these nominees and examine them based on different criteria, with an emphasis on the criteria people have claimed in the past made a difference about who gets nominated. First, by subgenre:

1 pop/rock act (ABBA)
1 vocal harmony act (The Chantels)
1 reggae act (Jimmy Cliff)
1 prog act (Genesis)
1 folk rock act (The Hollies)
1 metal/hard rock act (KISS)
1 rap act (LL Cool J)
1 girls group act (Darlene Love)
1 singer-songwriter (Laura Nyro)
1 alternative funk act (Red Hot Chili Peppers)
1 proto-punk act (The Stooges)
1 disco act (Donna Summer)

So, this year, like last year, each nominee represents a distinctly different subgenre of rock.

Next, by members. Question marks (?) wonders if these members will be added. Any members not listed will not be inducted:

ABBA (Agnetha Faltskog, Bjorn Ulvaeus, Benny Anderssen, Anni-Frid "Frida" Lyndstag)

The Chantels (Arlene Smith, Sonia Goring, Rene Minus, Jackie Landry, Lois Harris)

Jimmy Cliff (himself)

Genesis (Tony Banks, Mike Rutherford, Peter Gabriel, Anthony Phillips (?), John Phillips (?), John Mayhew (?), Phil Collins, Steve Hackett)

The Hollies (Graham Nash, Allan Clarke, Anthony Hicks, Eric Haydock (?), Robert Elliott, Bernard Calvert, Terry Sylvester, Mikael Rikfors (?))

KISS (Gene Simmons, Paul Stanley, Peter Criss, Ace Frehley, Eric Carr (?), Vinnie Vincent (?), Mark St. John (?), Bruce Kulick (?), Eric Singer (?))

LL Cool J (himself)

Darlene Love (herself)

Laura Nyro (herself)

Red Hot Chili Peppers (Flea, Jack Irons (?), Anthony Keidis, Hillel Slovak (?), Jack Sherman (?), Cliff Martinez (?), John Frusciante, Chad Smith, Dave Navarro (?))

The Stooges (Iggy Pop, Ron Asheton, Dave Alexander, Scott Asheton, James Williamson)

Donna Summer (herself)

Next, by previous inductions. Clyde McPhatter was the first person to be inducted more than once into the Rock & Roll Hall of Fame, as a soloist and as a member of the first incarnation of the Drifters. So, when someone is inducted more than once, we say he has joined the Clyde McPhatter club. So, notice the name in bold above? Poised to join the Clyde McPhatter club this year is:

Graham Nash, who is a member of the Hollies, and who was previously inducted with Crosby, Stills & Nash in 1997.

Next, by race:

White: 6, possibly 7
ABBA, Genesis, the Hollies, KISS, Laura Nyro and the Stooges. Possibly Red Hot Chili Peppers unless Cliff Martinez or Dave Navarro are inducted with them.

Black: 5 The Chantels, Darlene Love, Jimmy Cliff, LL Cool J and Donna Summer

Mixed: possibly 1
Possibly Red Hot Chili Peppers if Cliff Martinez or Dave Navarro are inducted with them.

Next, by gender:

Male: 28 at least and maybe up to 43, depending if any of the members with question marks by their names are inducted.

Women: 9

Next, by nationality based on place of birth:
One Australian (Flea of the Red Hot Chili Peppers)
One, possibly two, Israelis (Gene Simmons of KISS and Hillel Slovak of Red Hot Chili Peppers)
One Jamaican (Jimmy Cliff)
Four, possibly five Swedes (All the members of ABBA and Mikael Rikfors of the Hollies) Eleven, possibly sixteen, Brits
The rest were born in the United States of America, and by and large most of them were born in one of the burroughs of New York.

Next, by the number of top 40 hits on the Billboard 100:

ABBA: 14
The Chantels: 4
Jimmy Cliff: 2
Genesis: 17
The Hollies: 12
KISS: 9
LL Cool J: 14
Darlene Love: 2, unless you count all the hits she recorded with the Blossoms under other names
Laura Nyro: Of course not; that's why everybody else had hits with her songs!
Red Hot Chili Peppers: 7
The Stooges: 0
Donna Summer: 20

Next, by dead members. Currently, there are 5, maybe 6:

The Chantels (Jackie Landry)
KISS (if they include Eric Carr)
Laura Nyro
The Stooges (Dave Alexander, Ron Asheton)
Red Hot Chili Peppers (Hillel Slovak)

The previous two years, there were nine nominees, three of which were previous nominees. This year, there are twelve nominees, five of which were previous nominees. The nominators favor groups that have never been nominated over those who have, as do the voters.
