Lesson #2: Don't be afraid to cry
Maybe not literally this time, but a little bit of emotion might not hurt. When was the last time we saw Obama give a heartfelt speech about anything since Tucson?
The obvious anecdote for comparison here is when Clinton, tired from campaigning, cried before the New Hampshire primary in 2008 and wound up surprisingly winning by just a few points.
Obama had a perfect opportunity to reflect on his feelings last week in his gay marriage interview, but instead he explained his decision as a logical progression from conversations he had with his family and other parts of his "evolution." Needless to say, most gay rights activists were filled with emotion, even if he wasn't.
"Good politicians and the ones that are the most beloved show their human side," Siegel said.
Lesson #3: Lose the prompter
Yes, it's a tired rap on Obama that he reads from the Teleprompter all the time. That's not really the issue — all modern presidents use them. But sometimes it's good to speak candidly when the time is right.
Take a look at the beginning of this video of Clinton speaking off the cuff at the Women in the World Summit from March (make sure to catch the pantsuits joke). Compare that with this speech Obama gave in an elementary school classroom — behind a lectern, and two Teleprompters. "The Teleprompter clashes with Billy R.'s construction paper house," joked Jon Stewart.
It shouldn't be too hard for Obama to ditch the screens. In the scores of interviews and handful of press conferences he's given, Obama has proved he's not dependent on a script. And by giving a speech without a prompter, he might even suggest that he wrote it himself.
These are just small things that contribute to the image of Obama as a politician too reluctant to shed his shell. But voters choose their candidate in many ways, including general ways that they feel about the candidates.
In a Time poll last year, Clinton soared. While Obama beat Romney 46 to 43 percent, Clinton romped him 55 to 38 percent.
As Clinton said in her victory speech after the 2008 New Hampshire primary, "I felt like we all spoke from our hearts, and I am so gratified that you responded."
