Obama needs to add more substance to his call for change

As he did in New Hampshire, Obama seems to have failed to connect with Nevada's working class. Dante Scala of UNH observes:

Despite all the talk of her having had eight campaign slogans, Clinton managed to connect with working-class Democrats. Obama did not, with all the appeals to hope and change. That's part of Obama's problem; he appeals to [upper-class] voters who have the luxury of thinking about reforming the nation's politics. For working-class voters, it's more about healthcare.

More about healthcare -- and about a dozen other issues.
