Why are poor, uneducated Whites called “blue collar workers?”

By Earnest Gates 

As your daily politics watcher, it is my responsibility to raise concerns that are of interest to you. Since that is the case, I would like to pose a question: Why are poor, uneducated Whites called blue collar workers?

It is interesting to me that poor uneducated Whites get more credit and recognition than poor uneducated Blacks or Hispanics? As a matter of fact, most poor uneducated Blacks and Hispanics are not even thought of as likely voters. But not poor uneducated Whites.  Poor uneducated Whites are give a fancy title, like NASCAR dads.  Is something wrong with this picture or is it just me?

Why is it that when the Democratic primary came down to Pennsylvania, West Virginia and Ohio, poor uneducated Whites were the ones that everyone wanted Barack Obama to cater to? Do the poor make up a majority of the U.S. electorate? I’m just trying to understand what’s really going on.
