This week, audience members at a GOP debate cheered the prospect of letting an uninsured man die, prompting a Jon Huntsman staffer to say the outbursts made her "sick and sad" for her party. Other events of the week proved that "sick and sad" was an apt diagnosis: Mitt Romney -- clearly suffering from acute political delirium -- described Dick Cheney as "a man of wisdom and judgment." Pat Robertson, exhibiting all the signs of stage 4 moral decay, told 700 Club viewers that divorcing a spouse with Alzheimer's is okay because the disease is "a kind of death." Then there was John Boehner's classic case of voluntary memory loss, wherein he called job-creation policies he has supported in the past "short-term gimmicks." A two party system is in bad shape when one of the parties is so deeply sick. Is there a doctor in the house (or the Senate)?
