Actually I'm not well-read enough on the case to make that claim.
But clearly, the presence the firefighters have garnered on the talk-radio and the conserva-bubble more generally speak to the sympathy conservatives hold for the latest iteration in the Honest White Man Done Wrong by Liberals anthology.
And its this sympathy - which I am not sure is completely unfounded - that the GOP is using in a cynical ploy to discredit Sotomayor. That's out one side of their mouth. Out the other side is all the pablum about Sotomayor's quote about being a "wise latina woman", and how that means she'll use "sympathy" when dealing with illegal immigrants or other undesirables.
Given that her track record demonstrates clearly that she has NOT done so in the past, the bankrupt nature of these claims becomes all the clearer.
There are clear legal principles at play in the Ricci case: that's what should be discussed, not the sympathetic nature of the firefighters.
As to talk radio, you're right of course, sympathetic anecdotes are easier to sell than cold hard facts.
