There you go again. Palin is not claiming this is a new idea and I've yet to see anybody on this thread make the same claim.
Your point is ironic given your stated correction of Sarah on her mentioning "building roads and hospitals" as being inappropriate.
You misunderstand, then.
Recall what the fellow claimed above, "the difference is that people are listening to [Sarah Palin]."
The general flavor of the comments in favor of this piece is that Sarah Palin's engagement on the issue has somehow transformed it into an issue with real traction, where before it had none.
That is quite obviously false, which what I have been trying to point out. Sarah Palin has "transformed" nothing -- it's an issue that people have been working on, with some success, for a long time; and she is not alone even among current politicians in calling for tort reform.
Her article certainly doesn't offer any new information; the only "new" thing about it is Sarah Palin's attempt to inject herself into the issue; perhaps she even intended for her devoted followers to anoint her as a "leader" on the topic.
