Nice take. Their constituents should be alarmed that these control-freaks represent them.
The Democrat/left is opposed to Trump's wall b/c it takes control away from them.
They can control the information that comes from a virtual fence:
<><> They can choose to apprehend or not apprehend.
<><> They can make decisions in secret.
<><> They can manipulate the numbers of funded ICE agents available in a given area.
<><> They can control the fate of those apprehended.
<><> They can deport, catch and release, grant political asylum, even amnesty.
They'll do anything---even endanger Americans safety and security---to keep themselves in control.
