Excerpts from the 2008 Democrat Party Platform
We cannot continue to allow people to enter the United States undetected, undocumented, and unchecked. The American people are a welcoming and generous people, but those who enter our country’s borders illegally, and those who employ them, disrespect the rule of the law. We need to secure our borders, and support additional personnel, infrastructure, and technology on the border and at our ports of entry. We need additional Customs and Border Protection agents equipped with better technology and real-time intelligence.
We realize that employers need a method to verify whether their employees are legally eligible to work in the United States, and we will ensure that our system is accurate, fair to legal workers, safeguards people’s privacy, and cannot be used to discriminate against workers.
For the millions living here illegally but otherwise playing by the rules, we must require them to come out of the shadows and get right with the law. We support a system that requires undocumented immigrants who are in good standing to pay a fine, pay taxes, learn English, and go to the back of the line for the opportunity to become citizens. They are our neighbors, and we can help them become full tax-paying, law-abiding, productive members of society.
Definition: Infrastructure; The basic physical and organizational structures and facilities (e.g. buildings, roads, power supplies) needed for the operation of a society or enterprise.
In this case the “enterprise” is border security and the infrastructure is a physical barrier. Similar to what the Dems proposed and/or voted for several times since 2006.
