That includes races for the House of Representatives and U.S. Senate. The largest PAC, the National Association of Realtors, spent nearly $4 million on the election; that money was nearly divided between Republican candidates and Democratic candidates. The role of political action committees is, of course, to do just that: elect and defeat candidates. They do so by raising "hard" money and spending directly to influence specific taxes. There are limits on how much money an individual can contribute to a PAC and on how much a PAC can contribute to a candidate or a party. PACs must register with the Federal Election Commission. 01 of 10 National Association of Realtors The National Association of Realtors political action committee is consistently the largest contributor to political candidates at the federal level. In the 2014 mid-term election, it spent $3.8 million, leaning slightly to the right. It spent 52 percent of its money on Republican candidates and 48 percent on Democrats. The PAC, founded in 1969, supports "pro-Realtor" candidates, according to its website. "The purpose of RPAC is clear: Realtors raise and spend money to elect candidates who understand and support their interests. The money to accomplish this comes from voluntary contributions made by Realtors. These are not members’ dues; this is money given freely by Realtors in recognition of how important campaign fundraising is to the political process. RPAC doesn’t buy votes. RPAC enables Realtors to support candidates that support the issues that are important to their profession and livelihood." 02 of 10 National Beer Wholesalers Association The National Beer Wholesalers Association PAC spent $3.2 million in the 2014 campaign.

Honeywell makes aerospace and military products. Its political-action committee says its "engagement in the political process is critical" to the company's success. "Our future growth depends on forward-thinking legislation and regulation that makes society safer and more energy efficient and improves public infrastructure. For example, nearly 50 percent of our products are linked to energy efficiency. In fact, if our existing technologies were widely adopted today, energy demand in the U.S. could be reduced by 20-25 percent." 04 of 10 National Auto Dealers Association The National Auto Dealers Association PAC spent nearly $2.8 million in the 2014 campaign.
