In his attacks on Jeb Bush, Donald Trump has stolen a pagefrom Karl Rove’s playbook

In last week’s 8th Republican Party debate, Donald Trump attacked Jeb Bush by blaming his brother, George W. Bush for 9/11 and for the invasion of Iraq in 2003. US Centre Director Peter Trubowitz, writes that while Trump’s attack on Bush’s foreign policy is virtually unprecedented for a Republican, such tactics can trace their roots back to the strategy of George W. Bush’s political adviser Karl Rove, who argued that the best way to for politicians to defeat their opponents is to attack their strengths.
