This is actually old news but only today did I find out that the late Senator from Illinois, Everett Dirksen, never said this:
“A billion here, a billion there, and pretty soon you're talking real money.”See here, here and here.
But as with all famous quotes, someone had to make them up. Too bad only those with name recognition get attribution.
Update: It was only two months ago I was disappointed in these non-Lincoln quotes.
