Where is Congressman Steny Hoyer from? [A: Maryland]

Where is Congressman Tom Reynolds from? [A: New York]

Where is Congressman Denny Hastert from [A: Illinois]

OK, so where is Congresswoman Nancy Pelosi from? If you watch tv, the answer is always the same: San Francisco. Not California, but San Francisco. Hmmm. I wonder why that could be?
