A politician who proposes a wasteful pet project or pork barrel spending as used by Citizens Against Government Waste (CAGW).
Yearly publication of examples can be found at:
$98,000 to develop a walking tour of Boydton, Virginia. The politician who proposed this is called an Oinker by the CAGW. Though perhaps important to local tourism, it has little national significance and should be paid for locally, not with fund for the national common good.
$211,509 in olive fruit fly research in Paris, France. Unless these fruit flies are affecting the US crops, this research should probably be paid for by the EU or France, not American citizens.
