WASHINGTON—According to colleagues, 87-year-old senile Sen. Frank Lautenberg (D-NJ) has been allowed to believe he permanently solved the nation’s immigration crisis in 2007. “What’s the harm?” Sen. Mark Udall (D-CO) told reporters Tuesday. “He comes up and says, ‘It takes a lot to strike a bipartisan compromise on an issue as contentious as immigration, but I did it,’ and I just say, ‘You sure did, big guy!’ It makes him feel good.” Critics have argued that this is just another example of partisan favoritism, and that former Sen. Mark Hatfield (R-OR) should be allowed to think he is still a voting member of the Senate, or at least have access to the cafeteria.
