What song is this called? or the name of the band

I don't know why, but my original topic got closed, well here is the description again

I remembering watching this on fuse tv it was a music video to like a indie band... all I remember that it was placed in a school, and I think the lead singer wore glasses, and like he was running for class president, and while that was happening, a girl who was a band geek, liked the guy, but he didn't like her back, so she goes and leaves and the principal who was being rejected in school, starts playing guitar, and the girl finds the princepal and they start making a band in school, with her on the trumpet, I think, and the princepal on guitar... I saw this video 2 years ago, so I don't remember it well, and like, it involves flags, and at the end, the dude that was running for class president is beign chased in school and the princepal drives a yellow car and stuff, eh I hope this was descritptive enough...

thanks in advance.

what I know:
It has a indie/experimental rock feel
the person running for president wears glasses
The principal and a student becomes friends
I see flags
and it takes place in a school
