While this seems like a simple choice between the two, the ultimate fact is that without bills that address multiple issues, many bills wouldn't pass with bipartisan support. Bills are amended and reamended time after time before they are approved. Many of the improvements to the bill are concessions to one side or the other. Without these concessions bills might never pass, despite how crucial they actually are. Like it or not, bills addressing multiple issues are a critical part of how congress makes legislature, and they are here to stay, for good reason.
