Quite the opposite. The hard core Palinistas opinion is pretty much zero now. For the last 6-8 month, there has been countless vanities and blogs posted stating beyond a shadow of a doubt that she was going to run. Many analogies to Reagan '80 for why she was waiting till the last minute. Non believers in either her running or viability as a candidate were severely punished with hate and vitriol. Now the truth is known and the folks here who didn't have any emotional connection with any candidates and made objective observations have been vindicated.
Now we have a new round of tea leaf reading about what secret meaning this Palin announcement had. It had no meaning. She was weak in the polls, her movie and TV show didn't do well and there were already solid Conservatives running. This was all about whether she could win or not and nothing else.
