Michelle Obama, Cindy McCain are study in contrast

By Caren Bohan

WASHINGTON (Reuters) - Michelle Obama and Cindy McCain share a dislike of rough-edged U.S. politics. Each tried to talk her spouse out of running for the White House.

Obama, wife of Democratic candidate Barack Obama, and McCain, who is married to Republican John McCain, are both known for an elegant sense of style, lending glamour to their husbands' campaigns.

McCain posed in size zero jeans for the latest issue of Vogue. Obama, who has also appeared in the fashion magazine, was praised by style writers for the violet sheath dress she wore to her husband's Democratic nomination victory rally and has been compared to former first lady Jacqueline Kennedy.

But the aspiring first ladies have plenty of differences.

Obama, 44, is a Princeton- and Harvard-educated lawyer raised by blue-collar parents on the working-class South Side of Chicago. She would be the first African American U.S. first lady.

Obama talks often on the campaign trail about being a working mother. Until recently, she juggled a job as a hospital executive with raising two young daughters and lending support to her 46-year-old husband's political aspirations.

The strong-minded Obama exudes confidence and is an accomplished public speaker. But her penchant for outspokenness has also drawn some criticism.

McCain, 54, the Arizona senator's second wife, is reserved and seems far less comfortable in the limelight when she campaigns with her husband, who is 18 years her senior.

RODEO QUEEN

The blond, blue-eyed McCain is a former rodeo queen and cheerleader who holds a master's degree in special education from the University of Southern California. She grew up in a wealthy family in Phoenix and is heiress to Hensley & Co, one of the largest U.S. distributors for brewing giant Anheuser-Busch.

Last month, she released a tax return showing she made about $6 million in 2006.

McCain has raised four children, including a daughter Bridget, 16, whom she adopted from Mother Teresa's orphanage in Bangladesh. McCain has traveled the globe as part of her charitable work.

McCain's deferential manner puts her in the company of more traditional first ladies such as Nancy Reagan and Laura Bush.

"She is more in the classic mold of the candidate's wife on the campaign trail," said Calvin Jillson, a political scientist at Southern Methodist University in Dallas.

He said McCain has her own version of the "Nancy Reagan stare," the adoring gaze that the former first lady perfected.
