Now a billion $ is a lot of money -- but it used to be more in purchasing power. In the 1960s, the consummate politician, Senator Everett Dirksen (R), is reputed to have said: "A billion here, a billion there, pretty soon, you're talking real money." (Whether or not he actually said it is reputedly uncertain; see Wikipedia, here.)
Another Dirksen quote is: "I am a man of fixed and unbending principles, the first of which is to be flexible at all times." See Wikiquotes here. Dirksen, the Senate leader for the Republicans, could work with Democrats and get things done.
