I wondered something about America

If you notice, in many of America's songs and other stuff, he's saying 'Yes We Can!' (W.D.C World dancing, Marukaite chikyuu, WA WA World Ondo). If I'm correct the whole voice sound for America started back in january 2008. That was also the year that the U.s held their president elections. Barrack Obama's phrase was "Yes we can" (yea I actually remember it). Does anyone else find this odd? Maybe Himaruya-san actually took this phrase for a reason. Maybe it was just fate. I don't know. I was just thinking of this.
