The following is a list that I have compiled of the 10 most powerful LGBT- elected politicians in the world today. Six are gay men and four are lesbians. Included in the list are two heads of government (Belgium and Iceland), Germany's Foreign Minister, and the Premier of Ontario, the largest Canadian Province.
The list is subjective -- see my qualifications below. I did this list today when I found out the Prime Minister of Belgium was gay.
Please note- a candidate must be out, and freely publicize their LGBT status to be included.
1. Guido Westerwelle, Foreign Minister and head of the FDP Party, Germany
2. Elio Di Rupo, Prime Minister, Belgium
3. Kathleen Wynne, Premier of Ontario, Canada
4. Penny Wong, Commonwealth Minister for Finance and Deregulation and the Leader of the Government in the Senate, Australia
5. Klaus Wowereit, Governing Mayor of Berlin and Vice Chairman of the SDP Party, Former President of the Bundesrat, Germany
6. Bertrand Delanoë, Mayor of Paris, France
7. Iceland, Prime Minister: Jóhanna Sigurðardóttir
8. Nichi Vendola, President of Apulia Region, Italy
9. Rosario Crocetta, President of Sicily Region, Italy
10. Tammy Baldwin, Senator from Wisconsin, United States
(Note: Christine Quinn, Speaker of the New York City Council and leading Democratic Party Candidate for Mayor of New York was originally on this list. She was bumped to 11th position -- but will immediately rise up on the list if elected as Mayor in November, 2013).
Politicians must currently hold elected office to be on the list. Senior Justices are usually appointed and confirmed, and are not directly elected, and are not considered here.
Politicians must have acknowledged their current LGBT status in a positive manner to be on this list.
Allowance is made for national size. Germany, for example, is given more weight than Belgium since it is more than 7 times as large.
Allowance is given for length of time in office. Although Sicily is larger than Apulia in Italy, Nichi Vendola has been in office since 2005.
