The primary reason the democrats support illegal immigration has nothing to do with the labor force, although it's an excuse they've used for years. It's about politics and money. Ca. has been using it for years to manipulate the system. Even though illegals can't vote, they are counted in the census. The count is what determines the number of electoral votes that each state has. Note that Ca. has been losing millions of people over the past 10 years. That's why they're desperately attempting to illegally maintain the number of people in their state. Not only could they lose electoral votes, but they would stand to lose millions in gov. assistance. With red states benefiting from their loss of people, the dems. are in a state of panic.
