I suspect Republicans who belong to a union don't appreciate their money going to defeat candidates they support. Apply truth in advertising laws to political advertising. End the publishing of election polls a month before an election.
Polls are a lazy way of reporting the news.
Without them reporter would actually have to analyze the views of candidates. If nothing else the polling organizations with a bad record of predicting the outcome of elections should not be used by newspapers.

Require journalists to take at least on economics class in college so they know how the economy they're writing about so often is supposed to work. Give voters a little information to work with the next election when they're asked on a ballot which district, appeals and Supreme Court judge to retain in office.
