If only judged by stock holdings, I should probably be labeled as a pure Republican. I own Altria and Coca-cola outright, and also have a drug company (Pfizer, PFE) and an oil company (Conoco-Phillips, COP).

According to CRP's list, the most popular stock in Congress in 2005 (the most recent year data are available) was General Electric, which was owned by 103 Senators and House members. Rounding out the top five were Pfizer, Cisco Systems, Microsoft, and Intel—all household names and all stocks owned by countless mutual funds and large numbers of individual investors. "If you looked at any random group of investors in the country, this is probably what their portfolio would look like," says Jim Angel, an associate professor of finance at Georgetown University.

The data really start to get interesting when you compare stocks and party affiliation. For example, while 46 Republicans owned ExxonMobil in 2005, only 18 Democrats owned the stock. Republicans also preferred drug company Amgen, Altria, British Petroleum, and Coca-Cola in disproportionate numbers. As for Democrats, their preferred stocks include Texas Instruments, Vodafone, and drugstore chain Walgreens. A few stocks, such as media giant Time Warner and Seattle-based bank Washington Mutual, were split pretty evenly between the two parties. (Donut chain Krispy Kreme didn't make it onto the list of the top 50 stocks, but disgraced former Rep. Mark Foley had a sweet spot for the stock.)
