My experience of Baptist churches in our area is that they avoid the issue because it is controversial, and have no official teaching on it at all. When the issue is raised you have a few strong YECers, and a whole lot of OEC and TEs as well, the proportions depend on the particular church of course. My family had to leave a Baptist church over disagreements around creation - we are YEC and this was a big issue with some elements of the church, eventually had to just move elsewhere.
I can see how more traditional type denominations could be more supportive of TE though, given the fact that it is these denominations that are also going against the Bible in other ways such as in allowing homosexual ministers. These older Protestant denominations are becoming more liberal, so would be a comfortable place for people with liberal views such as TE.
