Where are you getting your figures?
In 2001 the President used to use the figure of 6 million illegals. Now he regularly uses 8 million which would be an astonishing 33% grow rate. In 2001 the most commonly number one heard as a believable estimate for illegals was 8 million. Now the Pew Charities is estimating just shy of 11 million and they put the growth rate at an alarming 25%. Many people think the PEW Charities, which is developing a liberal reputation for deliberately deceiving the public, is understating the problem.
In 2001, some believable sources were estimating the number of illegals as high as 10 million and a few sources that were generally considered extreme were estimating 12 million. In 2004, Time Magazine is estimating 15 million illegals and Bears Stearn is estimating 18 to 20 million illegals. Neither of these sources would be considered wacky or extreme.
It is not credible to say the number has not changed. Not even the open border types believe that. Pretty much everybody (except you) agrees that it is a growing problem.
My source is my memory. Your post cites widely differing estimates to conclude that I am wrong. Looks to me as if you can get statistics to say whatever you want. But no matter what the truth may be the conclusion doesn't change. Give me a break.
