Even Cornyn's amendment to Immigration Bill keeps troublesome measure of 90 percent apprehension rate

We are in trouble when even the best Senators don't understand the problems with how the apprehension rate is measured.

Republicans argue that Cornyn’s RESULTS amendment to secure the border is not radically different from language already in the bill. Both Cornyn’s proposal and the broader bill call for 100-percent monitoring and a 90-percent apprehension rate of illegal entrants along the Southern border. The crucial difference is that Cornyn’s amendment would require these goals be met before an estimated 11 million immigrants receive permanent legal status in 10 years. . . . .
