It may not seem right that former Rep. Michael Decker was able to pocket a $4,000 campaign contribution from House Speaker Jim Black. But it was legal.
It was also legal that Decker, before he was defeated for renomination in 2004, used campaign contributions to buy himself a new car and a plane ticket to go and get that new car. Or that he regularly used his campaign contributions to pay other personal expenses.
Don't point the finger only at Decker. What he did is common practice at the Legislative Building: Campaign contributions that go unused at the end of a politician's career can legally go into the politician's pocket and often do.
