Here is the wiki article about what I'm talking about, if you're lost.
I am extremely annoyed by how they are used, especially with their somewhat recent use in NDAA bills. The NDAA is essentially an annual bill which sets the U.S. Department of Defense's budget for the year, yet using riders there are often little things in the bill such as changing the rules for military detainment, and more recently a section which legalizes the use of propaganda.
The fact that such legislation can piggyback on something like a budget bill is extremely disconcerting to me, especially when you hear politicians saying things like this little gem of a quote from Nancy Pelosi...
So anyways, what do you think? Do you think it's right for unrelated, and often less agreeable, legislation to be able to piggyback on a larger, more supported bill? Do you even have an opinion on the matter?
