If logrolling is bad legislating such that the practice should be limited by single-subject rules. The question also asks whether a consequence of single-subject rules is to make it more difficult for minorities in a legislature (e.g., rural representatives, black legislators, an arts caucus) to build majority coalitions able to pass bills those minority representatives' constituents strongly support? also, the question asks whether this consequence of single-subject rules (i.e., their effect on minorities in legislatures) is a good consequence or a bad consequence. Can you assist with focusing the answer on these three parts of the question. Also, it is always a good idea to support an arguments with references, citations to cases, or illustrations. If you provide a citation for that support.
