What speech? It's a simple enough question. Where did you hear or read it? Where was it made? What is in it that is incompatible with Clinton's words in the email?
You can't mean this
http://www.nytimes.com/2016/07/29/us/politics/hillary-clinton-dnc-transcript.html, which is Clinton's acceptance speech. I thought it just might be, but it's not populism. It's a good speech, but far from rabble-rousing, and there's nothing about her father as a teenaged drapery hanger. He joined the Navy after Pearl Harbour and served the duration, so he wasn't a teenager when he started his own business.
There's a speech, then, but it's not
that speech. So please enlighten me.
