(MCT) — CONCORD, N.H. — Promising to champion the voiceless in Washington, President Barack Obama bounced from battleground to battleground on Sunday bringing an arsenal of famous friends to round up votes as the clock wound down on his re-election campaign.

With rallies in New Hampshire, Florida and Ohio, Obama entered the final 48 hours on the trail with a fresh vow to fight for the underrepresented and underprivileged. Grayed by the political battles of the past four years — “with the scars to prove it” — Obama said he would never surrender in the fight for the middle class.
