i hope that we have a presidential election where two great candidates are focused on the issues and have a good dialogue, not a petty partisan dialogue, but a good dialogue about what's going to make our country great. if that's going to be the kind of election we have, it's going told vat our nation. i think in that kind of contest, president obama will do well. >> mayor cory booker of newark, new jersey, mr. mayor, thanks for coming on and thanks for tweeting as much as you do. >> thank you very much. i appreciate it. >> join msnbc this sunday, august 14th at noon for a special two-hour program, "a stronger america: making the grade" hosted with tamron hall and jeff johnson of the grio. and you can be part of the conversation facebook.com/strongeramerica or follow us @strongeramerica use the hash tag making the grade.
