Making hay while the sun shines. The Midwestern American expression in the title refers literally to a farmer's maxim concerning the best time to cut your pastures. Figuratively, of course, it means to collect your profits in business or other enterprises when the time is right, whenever that might be.
Politicians also make hay.
Liberals seem to divide into two camps. The other part of the liberal Mob is the Control Wing, who are pushing for ever more involvement of the government in peoples lives and minds. This latter bunch are the more dangerous of the two, although the Complaining Wing relies upon the other to implement their various schemes to save us all from ourselves. Both wings have ardent followers, true believers to the core, but I trust the motives of the Complainers more than those of the Controllers. Conservatives too are split into two distinct camps.
