But try asking some of the most vocal on this issue about proposing a National ID card!!!!!!, But before you do, Put on some Nomex Jammies before hand :-)
In the long term, the only way this problem of illegals coming here for work will go away forever is when the Mexican economy grows enough that the attraction to come here and work is no longer worth it
Mexico has the potential to be a first world country, but first they have to throw off their corrupt oligarchy. Won't happen as long as we let them come into the US by the millions.
Closing the border and sending illegals home may actually encourage them to fix their problems.
