From her front row seat at the fall and spring fashion shows, a nod or frown from Anna Wintour can make or break what comes down the runway and send tremors through the fashion industry.

As one of President Barack Obama’s most successful fundraisers, the Vogue editor memorably played as a controlling ice queen by Meryl Streep in “The Devil Wears Prada” exerts her influence in another way.

In the run-up to the 2012 election, the British-born Wintour is part of an elite group of 27 Obama supporters who have used their connections to each solicit $500,000 for the president’s reelection campaign.... In less than a year of making fundraising calls and hosting a string of dinner parties, Wintour has more than tripled the $100,000-plus she helped raise for the campaign in 2008.

The fashion matriarch’s support for Obama is not a complete positive for the Obama campaign..... On one hand, Wintour, who was named the 69th most powerful woman in the world this week by Forbes, brings a certain panache to a campaign that promises to reach the billion dollar mark...... On the other, she highlights Obama’s celebrity ties at a time when the administration is tackling a down economy.
