The only 2008 poll I could find from them was released early October 2008, but appears to have been conducted mostly in September.
http://www.latinodecisions.com/blog/2008/10/07/new-poll-suggests-latino-voters-may-make-the-difference-in-four-key-states/They called Nevada 67-20 (actual 76-22)
Colorado 71-18 (actual 61-38)
New Mexico 67-23 (actual 69-30)
Florida 45-43 McCain (actual 57-42 Obama)
So they did pretty well in Nevada and New Mexico, but pretty poorly in Colorado and Florida, though they missed in opposite directions so their national number probably would have turned out okay.
