The Wasington Post quotes Obama as saying:
"Here in America, our success should not depend on an accident of birth, but the strength of our work ethic and the scope of our dreams. That's what drew our forebears here ... [that's] how the son of a barkeep is speaker of the House."
Would it be also possible to say in this context:
"and a scope of our dreams"
"a son of a barkeep is the speaker of the House"?
