This Pretty Much Sums It Up

One candidate, walking the streets, signing autographs, surrounded by enthusiastic supporters from all walks of life.
The other, indoors, greeting a captive audience of union members, trying to orchestrate a photo op in a near vacuum of enthusiasm.
Seriously, how much does the guy in the middle NOT want Martha Coakley to be touching him?
UPDATE: More "enthusiasm chasm" illustrated (via the Boston Herald).

Depends heavily on one's definition of "cheer".
