FILE - In this Nov. 23, 2009 file photo, Sen. Johnny Isakson, R-Ga., is interviewed by the Associated Press at the AP bureau in Atlanta. A question about why the government decided to issue a $6,500 homebuyers' tax credit only to those who have owned their current homes for more than five years inspired one of the questions in this edition of 'Ask AP,' a weekly Q&A column where AP journalists respond to readers' questions about the news.
