“Politicians and roosters crow about what they intend to do. Roosters deliver”

“Roosters crow, but hens deliver (eggs)” is an old saying. “Politicians and roosters crow about what they intend to do. The difference is, roosters deliver what they promise”—that is, the sun always comes up after the rooster crows—was cited in a 1991 newspaper.
 
American banker Frank A. Vanderlip (1864-1937) has been credited for the saying about politicians and rosoters, but there is no evidence that he ever said it.

Politicians are like roosters. To hear ’em crow, you’d think the sun was rising especially for them.

Just what gives with these left-wing Democrats? Perhaps the old saying: “Politicians and roosters do crow. But the roosters deliver what’s promised.”
