The prospect of Mississippi Gov. Haley Barbour (R) running for president next year "horrifies" his wife.

Barbour has been touring the country in recent weeks as he explores the possibility of mounting a presidential bid in 2012. One factor he'll need to consider is the toll that a long campaign will take on his family.

Mississippi first lady Marsha Barbour said the thought of Barbour's potential candidacy "horrifies me" because it would be "a huge sacrifice for a family to make."

Still, she said she would support her husband if he were to enter the race.

Asked about her comments, a Barbour spokesman told The Associated Press that Mississippi's first lady was simply stating a well-known fact: a campaign for president can be "daunting."

The two-term governor has said he will announce by the end of April whether he will enter the race for the GOP nomination.
