like turkeys voting for Christmas

Etymology
Because turkeys are commonly eaten at Christmas, turkeys voting for (an early) Christmas would be hastening their own death. The phrase is thought to have been (1944–1986) who used it to express opposition to the 1977. It was popularized by the British Prime Minister (1912–2005) who used it in the House of Commons in March 1979 when his Labour Party lost a vote of no confidence: see the 1977 and 1979 quotations.
