George W. Bush’s national security legacy is the ultimate sacred cow — that’s why Donald Trump is going after it

More than seven years after he left office, George W. Bush is back in the news after being attacked by Donald trump over his responsibility for the 9/11 terrorist attacks and the 2003 Iraq War. Peter Harris writes that Trump’s attacks follow a rehabilitation of sorts of George W. Bush’s reputation – at least among Republicans. He argues that the fight over Bush’s legacy is a microcosm of the broader struggle now taking place within the Republican Party which pits moderates – who are embracing Bush’s legacy – and anti-establishment Republicans like Trump who want to move on from what they see as the failed politics of the past.
