Sorry but no. Just because Bush failed to defend himself, does not make tRump’s Code Pinko statements okay. I would know more vote for tRump than I would for Cindy Sheehan. Both of them are self centered, evil people, who don’t care who they harm. Just as long as they win.
Forget about how Donald Trump may react, How do these words of George W Bush make the families of all those dead Americans feel when they see George W Bush saying this?
Secondly, George W Bush was NO conservative. Not even close. Next to Donald Trump he may appear to be conservative but that does not mean he's a conservative.
Bush did not simply fail to defend himself as you stated, he also failed to justify the great work our lost heroes had done fighting for this nation. It's NOT all about him.
