Mitt Romney's son, Josh, rallied Republicans at the campaign's Plymouth "victory center" Monday, the Star Tribune reported.
Thanking volunteers at a phone bank, Josh Romney said he loved being on the campaign trail for his father and added, "He's my hero."
The campaigns for Romney and President Obama have sent top surrogates to Minnesota in the final few days before the election on Tuesday. On Sunday, GOP vice presidential nominee Paul Ryan was in the Twin Cities, and former President Bill Clinton was in St. Cloud.
