John McCain yesterday, as quoted by The Boston Herald, concerned about the negative campaigning in the ongoing Republican primary battle:
“This is like watching a Greek tragedy. It's the negative campaigning and the increasingly personal attacks... it should have stopped long ago. Any utility from the debates has been exhausted, and now it's just exchanging cheap shots and personal shots followed by super PAC attacks.”
According to a poll published on Monday, Republicans have reason to be concerned :
McCain’s concerns come after a bipartisan POLITICO/George Washington University poll yesterday showed Obama’s job approval rising to 53 percent and all four of the Republican candidates behind by double figures in head-to-head matchups with the Democrat. Romney trailed Obama by 10 percentage points, while former U.S. Sen. Rick Santorum was behind by 11, the poll showed.
Adding......McCain endorsed Romney in January (those rich guys gotta stick together, ya know).
