“Republicans
  should be emphasizing the good things we’re trying to do  to try to  
help minorities vote instead of the things many minorities  feel is  
directed at them, rightly or wrongly.” 
In other words rather than  
clearly state what "is" is, he is suggesting they keep an agenda, but  
keep it to themselves, at least, I presume til after 2016. That seems to
  be the way the Republicans are going and Rand Paul probably  thinks it's important for him to get this message out now so he wont have to deal with it  
when he runs for president. I predict he will (barring something
  bizarre doesn't happen between now and then). Then, apparently,  the choice will be Republican Rand Paul or Republican Rand Paul Lite.
