Unless I missed it, immigrants are not mentioned in either the local or national issue polling of Middle Tennessee State University this year (poll page here). (H/T: Tennessean)
Immigrant-related issues were mentioned in MTSU's 2003 (story here), 2004 (story here), and 2006 (story here) polls.
The most recent Nashville poll related to immigrants was in the form of a city-wide election on January 22, 2009. (See Nashville for All of Us.)
