It is far more likely than not, that the two sentences being parsed to hell & back, today, were not copies of someone else's writing.
The concepts in those sentences are such common place comments, that the cliches under-discussion have been applied literally thousands of times--maybe millions of times--in very, very similar contexts, in public discourse. Just how many distinct ways can anyone describe the instilling of values in a family. It is virtually impossible to actually do so in a unique manner. But one does not need to copy anyone else, to end up unwittingly copying a great many "anyone else's.
Let us not lose sight of the fact that Mrs. Trump delivered her address--which had a great deal more to it than those two over analyzed sentences--with warmth, sincerity & an effectiveness that neither Mrs. Obama or Mrs. Clinton could ever--ever in their lives--hope to match.
Do not lose sight of the fact that this speech was a great asset to the campaign. It should be played again and again in the campaign.
As I said the speech was flawless - America - American Pride - American Values. You and I know that is not what is being reported today. Instead snippets that had little bearing on the overall speech are being played over and over again. It wont sway my vote. I’m not voting for 1st lady. But how will this play out with the average low info voter? And how much has it taken the attention off of the other outstanding speakers. As mentioned earlier, Sen. Sessions speech has not been mentioned at all. What about Rudy or Mrs Smith.
