Hillary Clinton’s increasing Democratic primary advantage in states like New Hampshire and Iowa can also be seen in her remarkable turnaround in general election matchups. Looking only at how Obama and Clinton, the two Democratic candidates who have opted out of public financing, fare against Rudy Giuliani (Clinton data here, Obama data here), check out how Clinton moves from performing significantly worse, to performing the same, to performing better over the past eight months:

Note: Only polls that collected data on Clinton vs. Giuliani and Obama vs. Giuliani in the same survey are included, as those are the only apples to apples comparisons possible.
In nine of the ten oldest polls in this chart, from March 26th through June 10th, Obama held a general election advantage over Clinton. At that time, the Marist poll showing Clinton with an advantage was clearly an outlier. However, over the next fifteen polls, from June 11th through today, Clinton held the advantage in twelve polls, two were tied, and the GW Battleground poll weighed in with a clear outlier. (As they say, one out of every twenty polls is way off, and so the presence of two outliers in this chart is not anomalous.)
At a quick glance, I am seeing three periods in this chart, the first showing Obama with about a six-point edge (late March through early June), the second showing a virtual tie (mid-June through early August), and the third period showing Clinton with a modest advantage of about four points (mid-August through today). Overall, Clinton has improved her performance against Giuliani relative to Obama by about ten points over the last seven months. It is entirely possible that will reverse itself at some point, since the five months of general election polling before this chart, Clinton actually started with the advantage in November 2006, but Obama caught up and passed her over the next five months. Then again, it is possible that Obama’s rise from comparative obscurity meant that his favorable ratings hit an all-time peak around March and April of 2006 during his “rockstar” media coverage phase, and now they have inevitably fallen a bit. That, combined with slowing lowering opinions of Giuliani and slowly improving opinions of Clinton, could also produce the trends we see here.
