It's not surprising that 10 of the Democratic candidates running for president would jump at the chance to appear before the nation's largest labor union.  The National Education Association held its annual convention in Houston this year.  Part of the days-long event was a forum with the candidates.  This is the second such forum featuring a number of Democratic candidates that I've covered here in recent months.  Many expect other visits by Democratic candidates as Texas turns more and more purple.
