Rep. Joanne Favors and State Senator Thelma Harper were chatting together as Judy and I left the hotel to go to dinner . Joanne has been an Obama supporter , and Thelma was an ardent Hillary supporter . Thelma introduced both Bill and Hillary Clinton when they made separate appearances in Nashville . But it was quite obvious that , presidential preferences aside , Thelma 's and Joanne 's friendship and goals remain strong . What is most apparent to me is that whether we preferred Hillary or Obama , we are all part of the Democratic family .

Answer the following question: Why would Joanne and Thelma be cooperative despite their differences ?
They are still Democrats .
