off the dime

I've been mentioning a lot of British idioms and slang that I hadn't previously encountered; now here's an American one.

The compromise proposal [...] was introduced last night and "has moved this issue off the dime," said Sen. John McCain (R-Ariz.)[....]

--Washington Post, "Immigration Legislation Compromise Announced," by William Branigin and Jonathan Weisman, 6 April 2006

Don't think I've ever seen that before. Answers.com's idioms section says to "get off the dime" is to "Take action, especially following a time of indecision or delay." Claims it's from 1920s dance halls, though that sounds a little dubious to me.
