Money in Campaigns

Describe the significance of money in in a modern presidential election campaign.  How does the government regulate the fund-rasiing and expenditures of presidential campaigns?  Is the government regulation adequate? Explain

      Money rules the world of politics. And the modern presidential campaign. Tv advertising alone surpassed two billion in 2012. Without this money candidates would not be able to campaign like they do. So where does this money come from? Supporters, many through 501-C4's so that you can not see who gave what. This can be an issue because government favors come into question. The government does very little to regulate fund raising. The government does put caps on amounts of money one can give a candidate. But there are ways around this such as bundling. The government could constantly regulate money sources but this is a lot of work and our government seems to have bigger things on their hands.
