Personally, I haven't made up my own mind on whether campaign contributions need more limitations than they currently have. I hate the rash of negative advertising, but limiting contributions just means that only the rich could afford to run.
The key problem with this proposed amendment is that it is way too broad. It authorizes the legislature to enact laws prohibiting contributions and expenditures of ANY TYPE OR DESCRIPTION intended to influence the outcome of ANY election. That doesn't mention money. This could very easily be used, for example, to prohibit candidate endorsements in newspaper editorials. It could easily be used to prohibit me from making these very blog postings.
No. Constitutional amendments must be specific, carefully worded, and clearly beneficial to the state as a whole. This one is NOT.
Vote no on Measure 46.
