Republican presidential contender John McCain has been endorsed by both of Mitt Romney's hometown newspapers, a blow to the former Massachusetts governor who often taunts his opponents with negative e-mails titled, "Those who know him best." The Boston Herald, the conservative tabloid in Massachusetts, endorsed McCain for president in an editorial posted online Thursday. "There are times in this nation's history so perilous that they cry out for a steady, experienced leader, a person so trusted that we would put the fate of this country in his hands. This is one of those times, and Sen. John McCain is that person," the newspaper said. It did not mention fellow candidate Romney, who led Massachusetts from 2003 to January of this year.
