Of course only preliminary but rasmussen has found that, at this stage in the Palin roll out, she adds little support for McCain.
According to the poll 35% of voters are more likely to support McCain due to Palin's choice as running mate and 33% of voters are less likely to support McCain. Some might say that it adds 2 points of support and that is good but a 2 point difference is statistically insignificant. So as of today, all we can say is that the choice is a wash. Might change, who knows? This could either be the high point in her support, due to the buzz generated but will taper off as time goes on or it could be that people will like her more as they get to know her.
And if you want to know a little more about who she is appealing to, it may be surprising to you that she appeals to men but not really to women.
