Weiner rose through New York City politics as a young man unafraid of a fight and eager for media attention. Abedin, in contrast, is known for her diplomacy and privacy.
In her own words
As Weiner's latest scandal unfolded, Harper's Bazaar published excerpts of an article Abedin wrote for the magazine.
"Three years ago I was a single workaholic, traveling the globe with an amazing job at the U.S. State Department. I could not have imagined how much my life would change in three short years," Abedin wrote for the magazine's September issue.
"Today I'm married, with a feisty 20-month-old son, a full-time job, and a husband running for mayor of New York."
Abedin said she has long kept her personal life private, and no one is more surprised than she is to see herself out on the campaign trail.
"So why am I doing this? Because Anthony has always been a smart, caring, and dedicated person, and while he's the same public servant who wants what's best for the people he represents, he is now something else -- a better man," Abedin wrote.
"New Yorkers will have to decide for themselves whether or not to give him a second chance. I had to make that same decision for myself, for my son, for our family. And I know in my heart that I made the right one."
