What a gentleman. Cheats on his wife. Lies about it to her, his staff, the American people. Then tells her after he’s already announced his second campaign for president.

J-Ed, you didn’t think perhaps you owed it to your wife to at least confess before deciding on a second grueling national campaign? Instead you put her in a position where she had no choice but to suck it up and stand by your side. Your kids must be proud.

And to you, Mrs. Edwards, I have just two words: Lorena Bobbitt.

Actually, I have four more: It’s not too late.

Elizabeth Edwards writes about husband’s affair in book, ‘Resilience’

BY Celeste Katz

Campaign cad John Edwards’ cheating ways made his wife, Elizabeth, sick to her stomach – literally.

After the former presidential hopeful confessed his betrayal, Elizabeth Edwards writes in her new book, “I cried and screamed, I went to the bathroom and threw up.”

Elizabeth, 59, who is terminally ill with cancer, speaks in far more detail than before about her husband’s infidelity in her new memoir, “Resilience,” due to be published May 12 by Broadway Books. A copy was obtained by the Daily News.

Despite feeling deeply deceived, Elizabeth Edwards nonetheless publicly stood by her husband’s side, lending his candidacy the aura of a warm, loving family life.

But she had actually wanted him to quit the race to protect the family. Edwards admitted the hanky-panky to her days after declaring his candidacy in 2006 – almost a year before the National Enquirer reported it.
