Bait (sex) and switch (politics)

She's "breaking her silence" about her husband's adultery to get more publicity for her liberal agenda:

Elizabeth Edwards appeared Thursday morning on Capitol Hill where she discussed the need for heathcare reform in front of the Committee on Energy and Commerce's subcommittee on Health. Edwards veered from her prepared remarks to attack Republican presidential nominee Sen. John McCain on his healthcare policy.
"Neither one of us would be insured under his healthcare plan," she told the committee, an attack she has used frequently against the Arizona Senator, who was diagnosed with lymphoma in 2000.
"I do think that Sen. McCain's policy does focus excessively on providing a lower cost policy without at the same time guaranteeing a basic level of coverage in that policy or addressing the scope of inclusion for all Americans," Edwards elaborated.

She is, if nothing else, amazingly consistent. All she has ever cared about is politics.
