Interpersonal communication between candidates and voters

Interpersonal communication is the way candidates connect with voters on an emotional, human level. Face-to-face, one-on-one contact initiates a cascade of barely perceptible and even unconscious nonverbal cues, which contain a rich lode of information that influences perceptions.
For quite some time now, I've been noticing some serious gaps in Barack Obama's communication skills. It didn't seem possible just a few short months ago, but it's started to look like Obama has a "tin ear" when it comes to interpersonal communication. It's the little things that have been bringing him down: the flubbed diner and small-town shop visits, snapping at reporters while on vacation or eating breakfast, the lame attempts at flattery and flirtations with humble voters that Obama confuses with small talk. The everyday patter that is the heart of a campaign as well as of life makes him ill at ease and unable to be spontaneous. Worse, he seems to be unaware of how this skills deficit impacts him and his campaign.
when Hilary was running for president i really like how she communcated and interacted with the people. She cames across as warm and generous, seeming always to have time for another hug or photo or to listen to another story.
