"Inauthenticity is endemic in American politics today," wrote McGreevey, in excerpts released by publishers. "The political backrooms where I spent much of my career were just as benighted as my personal life, equally crowded with shadowy strangers and compromises, truths I hoped to deny. I lived not in one closet, but many."
"Ironically," McGreevey continued, "the dividing experience of my sexuality helped me thrive in that environment. ... I kept a steel wall around my moral and sexual instincts. This gave me a tremendous advantage in politics, if not my soul."
Worries that politics is riven by inauthenticity are nothing new, and some commentators and former McGreevey colleagues say the importance of McGreevey's "Confession" may be more personal than universal.
"McGreevey allowed his deeply personal conflicts to cloud his duties as a public official to the peril of the people he was elected to serve," said Mintz, adding that he believes "most of the voters in New Jersey have turned the page on that chapter in our state's history and would prefer to move on."
"McGreevey handled the situation about as well as he could, given his position," said Tom Nelson of the Philadelphia chapter of the Gay Married Men's Association.
Nelson, who runs Gamma support groups, told ABC News that McGreevey's coming out again now in so visible a way will make more Americans aware of a reality more common and painful than they realize.
"Most married gay men tend to stay married -- at first," said Nelson, who estimates that at least four out of five sooner or later end their marriages.
Goldstein, who also works with Gamma, said the publicity around McGreevey's new revelations may do a little good if it "gets more people talking, and [straight] people need to talk more to the gay people in their lives."
McGreevey's publishers have said he book "names names."
Just how much political chicanery the lawyers may allow McGreevey to reveal won't be evident till late Tuesday.
The excerpts already released make it clear that McGreevey received considerable freedom in revealing personal details.
The counterattacks between McGreevey and his publishers, and Cipel and his lawyers, have not run out of steam, with each side calling the other liars and hurling imprecations about "deceitful ambition" and "special places reserved in hell."
