Jake Tapper on ABC's 'Good Morning America': 'Senator Clinton will be speaking to one of her most loyal constituents today: white working class families. ... While Obama may be fashion-forward with his open collars, he's having a real problem with blue collars. ... Many white voters who support Obama are elites, like the U2 that plays at his rallies. ... Clinton plays Dolly Parton's working class classic, '9 to 5.' ... Obama's scrappier competitor may be a millionaire but she plays up her working class roots.'
