That is a lie, if it were true Trump would never have been elected with his hard line stance on illegal immigration. If the numbers of support were significant at all DACA would have already been made permanent with all sorts of goodies attached. The reason the Democrats would not touch it when they were running the show, the reason Obama did a temporary fix was because the support was not there- even among Democrats! The kind of support he is claiming has not existed for many years if it ever did.
At one time I believe there were large numbers of people supporting DACA and other "perks/rewards" for illegals. That ship sailed as the nation began to fill with illegals in every nook and cranny. At that point we the people realized we had been lied to about how great illegal immigration is for this country.
DACA is far down on the list of our problems. They will never be deported, so forget about that. Very few would support it contrary to the beliefs around these parts.
Ending chain migration and building the wall would make Illegalism as a major problem much more tractable. DACA becomes relevant AFTER the willing illegals are deported.
It is at the tail end of the 8-30 million illegals and will be handled accordingly. Prioritization is of utmost importance.
I agree, even my most liberal friends are against DACA.
