Christina Aguilera’s new ‘Rock the Vote’ public service announcement has just hit the airwaves. The 27-year old powerhouse singer is features cradling her now 6-month old son Max Liron, swaddled in the American flag, as she sings the a capella version of ‘America the Beautiful’. ‘Rock the Vote’ works to engage the youth in the political process by incorporating the entertainment community and youth culture into its activities. With the importance of this year’s elections, having some of the most influential figures for the younger generation featured in the PSAs should hopefully prove to be helpful.
