History will tell if Minnesota breaks its 36-year streak of voting for Democrats in presidential elections, but Josh Romney, one of GOP candidate Mitt Romney's five sons, was rallying the Minnesota Republican faithful Monday at a gathering in Plymouth. Accompanied by two of his own children, the younger Romney donned a casual sweater and blue jeans to thank volunteers at a Republican phone bank operation that is trying to turn out the vote for his father and flip Minnesota away from President Barack Obama, who leads in the state. "I love being on the campaign trail for my dad," Romney said. "He's my hero." Republican National committee (RNC) Chairman Reince Priebus helped rally the conservative troops at another rally later in the day in Burnsville.
