How Would You Choose a Math Textbook?

Many districts and schools are deciding which math textbook to choose.  In researching the effect of textbook choice upon student achievement, there is little reliable research available.  Only two states have collected data so making curriculum decisions based on research is extremely thin.  The most "popular" curriculums are Saxon Math, Silver-Burdett Ginn Mathematics, and Scott Foresman-Addison Wesley Math.  So how have states/districts made curriculum decisions?  To answer this question please reference the frank remarks quoted by Beverlee Jobrack, author of The Tyranny of the Textbook.  She explains the educational publishing industry is driven by "sales and marketing teams."  Problem: 
How in the world will decision makers align curriculum to Common Core Standards?  Do you question statements from various publishers, "Yes, we are aligned to Common Core Standards."  Who needs to look deeper?
