This is something that should be of great interest for you to pass around. I didn't know of this until it was pointed out to me.
Back during the great depression, Herbert Hoover ordered the deportation of ALL illegal aliens in order to make jobs available to American citizens that desperately needed work.
Harry Truman deported over two million illegal aliens after WWII to create jobs for returning veterans.
In 1954 Dwight Eisenhower deported 13 million Mexicans. The program was called Operation Wetback. It was done so WWII and Korean War veterans would have a better chance at jobs. It took two years, but they deported them!
Now, if they could deport the illegal aliens back then, they could surely do it today. If you have doubts about the veracity of this information, enter Operation Wetback into your favorite search engine and confirm it for yourself.
Why, you might ask, can't they do this today? Actually the answer is quite simple. Hoover, Truman and Eisenhower were men of honor, not untrustworthy politicians looking for votes!
