And former Clinton campaign aides say there was internal discussion of plugging Clinton directly into the nascent social media in 2008, giving her a Twitter account and letting her be as warm, smart, and funny in public as her friends — dismayed by her portrayal as alternately shrill and robotic — always said she was in private. Some aides still think it could have changed the game.

"I think social media could have helped her in 2008. It would have provided a more powerful outlet for her supporters," said Judd Legum, Clinton’s research director that year and now the chief of the liberal media outlet ThinkProgress and author of its giant Twitter account.

Then, he said, social media could have leveled the media playing field.

"The people who are running the sites in the progressive and liberal blogosphere favored Obama. Her supporters would have had more of a voice,” he said.

"Had social media been around to the degree that it has evolved today, it would have allowed us to have shown a little more of Hillary and we would not have relied as much on traditional media outlets," said Phil Singer, a top Clinton press aide in 2008. "People would have seen her without out the filter in the press."

Now, the hobbled frontrunner of 2008 is the most popular official in the Obama Administration, and the darling of the national media. Consider some recent newspaper headlines about Clinton. There was "Queen Of Cool," an April 2012 Op-Ed by Maureen Dowd in The New York Times. And MSNBC, the same network that so readily slammed her in '08, featured a segment that same week in which anchors excitedly called Clinton "the Secretary of Cool."

There are three key factors in Clinton’s new sky-high popularity — new Gallup poll numbers show her approval rating at 66% — and her emergence as an online celebrity.
