Okay, now that you've read what that web page says, here is what another web page says...

Who said 'You can fool all the people some of the time and some of the people all the time but you cannot fool all the people all the time'?
Answer:
It is commonly attributed to Abraham Lincoln, but there appears to be no hard evidence that he actually said it. It has also been attributed to P. T. Barnum (of the world famous Ringling Bros. Barnum and Bailey Circus), poet John Lydgate and Mark Twain.
There is also a variant (sometimes claimed to be the original form):
"You can please some of the people all of the time, you can please all of the people some of the time, but you can't please all of the people all of the time."
However, Alexander McClure attributes the quote to Lincoln in his 1901 book Lincoln's Own Yarns and Stories. McClure (1828-1909) was a personal friend of Lincoln and was appointed Asst Adjutant General by Lincoln. He also worked on Lincolns 1860 election. I could find no credible source attributing the quote to Barnum.

So here's what we have. That first web page I gave you is emphatic that Lincoln never said it.
BUT, the web page I'm giving you in this post implies that since it was a personal friend of Lincoln who attributed the quote to him the implication is that he DID say it.
The point is that what we will believe will depend on which page on the internet we read. Read one and you believe one thing. Read the other and you believe something else. And since we rarely ever read contradictory claims we will believe something without having benefit of the counter claim.
In other words, this may be an "information superhighway", but often it's nothing more than just a bunch of opinion masquerading as fact.
