The marriage of John and Cindy McCain has mixed business and politics from the beginning, according to an expansive review by The Associated Press of thousands of pages of campaign, personal finance, real estate and property records nationwide.

As heiress to her father's stake in Hensley & Co. of Phoenix, Cindy McCain is an executive whose worth may exceed $100 million, and beverage industry analysts estimate Hensley's value at more than $250 million, with annual sales of $300 million or more. Hensley describes itself as the third-largest Anheuser-Bush wholesaler in the United States.

• Within a few years of marrying Cindy Hensley, the daughter of a multimillionaire Anheuser-Busch distributor, John McCain won his first election. He was new to Arizona politics and fundraising in the 1982 House race, and his campaign quickly fell into debt. Personal money -- tens of thousands of dollars in loans to his campaign from McCain bank accounts -- helped him survive.
• Anheuser-Busch's political action committee was among McCain's earliest donors. Cindy McCain's father, James Hensley, and other Hensley & Co. executives gave so much the Federal Election Commission ordered McCain to give some of it back. McCain's campaign used Hensley office equipment such as computers and copiers, and Cindy McCain personally paid some of the campaign's bills.
• Hensley executives are among the Arizona senator's top career givers. The Anheuser-Busch PAC has given McCain's campaigns at least $19,500 over the years. McCain's campaign fundraisers include Robert Delgado, Hensley's president and chief executive officer; Andrew McCain, the company's chief financial officer and John McCain's stepson from his first marriage, to Carol Shepp; and August Busch III, chairman of Anheuser-Busch's executive committee. Anheuser-Busch in 2006 gave $25,000 to the International Republican Institute, a pro-democracy group chaired by McCain.

The National Beer Wholesalers Association political action committee doles out millions of dollars to Democratic and Republican congressional candidates each election. John McCain's campaigns have received at least $26,000 from it over the years. An informal poll on the trade group's Web site asks visitors which presidential candidate they would most like to have a beer with (Democrat Barack Obama was way ahead in late March with 45 percent, McCain was second, with 23 percent). The connection to McCain hasn't helped the beer lobby in Congress, AP reported.

• McCain has long said he refrains from voting on beer industry-specific issues. Following that policy, McCain voted "present" when the Senate voted in March 1998 to withhold state highway funding from states that failed to adopt a .08 blood-alcohol standard for drunken driving.
• Two years later, McCain voted against the fiscal 2001 transportation appropriations bill, which set a national .08 standard. The National Beer Wholesalers Association opposed the legislation and told its members it had at least succeeded in "delaying and diluting the final version." McCain voted against the bill because he objected to "pork-barrel spending," Hazelbaker said.
• Beer wholesalers and other businesses tried unsuccessfully to block a campaign finance law that McCain co-sponsored banning corporate contributions to the national Democratic and Republican parties. On another top business issue, the estate tax, McCain has supported cuts but opposes permanent repeal. Beer wholesalers contend a repeal would help save family businesses like Hensley.
