boodler

One, especially a politician, who seeks or receives boodle; a political grafter.

Boodlers, according to the dealers in boodle, are divided into two categories, the honest and the dishonest boodlers. The honest boodler is the alderman who, when bought, stays bought,' and does not sell out to the other side; the dishonest boodler is perfectly willing to take money from both sides and dispose of his vote, not according to the first bid, but the last.

I guess it kept him reminded about his graft whenever he saw the siren voice of the boodler tip him the wink with a bribe in its hand.

A person displaying unsportsmanlike behavior.
