Barack Obama has used "Yes, We Can!" as his rallying cry and it's not an accident. Team Obama has sampled and remixed the "¡Sí se puede!" chant that César Chávez and Delores Huerta came up with for the United Farm Workers. Their presence still echoes today via La Campesina Radio Network, initially established by the UFW with the help of Senator Robert F. Kennedy. Chávez's youngest son, Anthony, acts as its current president. In addition to keeping farmworkers up to date, they keep things moving with quite the palette of regional Mexican music, even landing legendary Mexican performer Vicente Fernandez as a DJ.
