The prospect of amnesty is what keeps 'em coming

So says the president of Honduras:

The president of Honduras, Juan Orlando Hernandez, recently said that the tidal wave of illegal immigrants crossing into the U.S. from Central America can be attributed to the fact that many believe they will get amnesty. The Obama Administration's rhetoric and actions surrounding the immigration surge have led many in Central America to think they will not be deported if they come into the U.S. illegally--and indeed, most of the thousands of children that continue to cross the border will likely get to stay in the country. 

Why is the message to these people not unmistakably clear that there will be no amnesty?  What is the real reason? 

Perhaps we should ask Valerie Jarrett and Rupert Murdoch.
