Amnesty is to the Hispanic vote what the carrot on a stick is to the mule

Obama is putting the amnesty carrot on a stick so as to keep the Hispanic mule voting in the right direction, which goes nowhere

The real explanation may be related to the tendency of his party to avoid solving issues important to their base. One may ask: if the president really thought that his party would permanently capture the Hispanic vote with an amnesty type Congressional bill in his first two years, why didn’t they pass such a law? --- Michael Bargo, Jr  AmericanThinker 

Such may regarded as a principle of operation that can be applied to a large cross section of the public, of which the Democrat party only uses for their own advantage.  They do nothing to serve the public, which for some strange reason, trusts them.
