You can send ABC feedback, for what it might be worth, from THIS PAGE, though I see that is supposed to be just for the online news. If you really want to stir them up, it looks as though someone needs to start a discussion thread about it on their Forums' Page

There's more about how this came about from AP.

Here's a snippet: The network set rules to narrow the field. Candidates had to meet at least one of three criteria: place first through fourth in Iowa, poll 5 percent or higher in one of the last four major New Hampshire surveys, or poll 5 percent or higher in one of the last four major national surveys.

Democrats Joe Biden and Chris Dodd took some of the pressure off ABC by quitting the race Thursday night.

"In previous debates where the stage was more crowded you had to make sure all of the candidates got fair time," said David Chalian, ABC News political director. "Here you will have more time to go in depth on the issues."

ABC said it believed its rules were inclusive, while also ensuring viewers get a thorough look at the probable next president.
