Well too much time - I guess time may tell. But I think the phrase "everyone remembers" is HIGHLY suspect. It has been my experience that people, in general, have a pretty short attention span.
And in terms of her "dominating the healthcare debate" with a couple of blogs - that is highly suspect as well. You could just as easily argue that the former NY Lt. Gov. (who actually coined the phrase "death panels") was able to "dominate the debate" with a fairly obscure little statement. The fact that Palin, Grassley, and several others picked up that ball and ran with is not exactly a sign of political clout imho.
and non-rassmussen polls aren't nearly as good for Palin:
"A solid majority of Americans don’t want to see Sarah Palin ever become president, according to the latest Wall Street Journal/NBC News poll.
Two-thirds, 67%, said they don’t ever want the former Alaska governor to be president, compared with the 21% who said they would.
While it should come as no surprise that 87% of Democrats said they don’t ever want Palin as commander-in-chief, some 43% of Republicans said the same thing—as well as 65% of independents.
Even 46% of self-identified conservatives said they do not want Palin as president, as well as 44% of those who voted for Arizona GOP Sen. John McCain in 2008.
At 44%, white evangelicals are the largest subgroup supporting Palin as president one day."

BUT - I do think you've hit upon her recipe to try to turn those numbers around. But RIGHT NOW she stands at about 21% and I think reminders of her very poor performances could bring that number right in line with the 10% to 15% figures I used earlier. And the other side of the coin is also possible: With coaching and a lot of re-hab work, she might be able to do better than 21%.
