Answers to that question could easily be written in the length of a book, let alone a blog post, but we'll attempt to do some minor justice here.

The short answer? A big one.

Just yesterday, Bill Clinton told the Huffington Post that writer Todd Purdum of Vanity Fair was a "scumbag," following up with, "...this has been the most rigged press coverage in modern history," in response to a story Purdum penned about his personal affairs and wife's presidential campaign.

This led spokesman, Jay Carson, to release an apology statement on the same day Hillary Clinton (conceded?) the nomination to Barack Obama.

Meanwhile, Minnesota GOP Chairman, Ron Carey claimed on a media conference call, "Barack Obama is still largely unknown, and events like this [last night's speech] will show the real Barack Obama, not the PR machine."

It seems like years ago (it was only two months ago) that Burson-Marsteller CEO Mark Penn quit as Hillary's top strategist. Many claimed his "micro-trends" lost out to Obama's "macro" messages of unity and hope.

Social media news site Mashable takes a closer look at each candidates online strategy, claiming Obama, "placed a PR emphasis on connecting with his base nation-wide, and is considered the young, hip candidate on the Democrat side."
