And that is EXACTLY what he has said: That a wall is not going to keep them out, that conservative ascendancy will -- that all the liberal social engineer programs that support them here (and allows them to send money back in many cases) will keep bringing people here.
And I will point out to you that since the states cannot ask if a student is in the country legally by the time they've graduated from high school (min 3 years in Texas public school and graduated to be considered) it is prudent to allow THEM to PAY instate tuition to attend college if they can and have a better educated Texan (as they do apply for citizenship). Many of these children that are brought by their families are basically without a country.
There is no way around this until the border is sealed. This is a matter of geography that most other states DO NOT have to deal with (I am speaking about the 1250 mile border -- where there is crime and that Texans are spending about $100 Million a year from our state budget to patrol as much as we can).
Taxpayer paid tuition for illegals is NOT making things unfavorable to wetbackery.
