Obama Misleads On Women's Pay

Article here. Excerpt:

'Last week, the Senate voted on the Paycheck Fairness Act, Democrat-created legislation that would have allegedly insured women are paid equally to men. Democrats cited statistics indicating women only make 77% as much money as men do as justification for the new legislation. The Senate voted down the legislation basically along party lines, with Republicans and a handful of Democrats voting against it.

Color me confused. Didn't President Obama sign the Lily Ledbetter Fair Pay Act of 2009 to address that exact problem? Is this new legislation an admission that Ledbetter was ineffective, or what? Plus, the Equal Pay Act of 1963 was implemented nearly fifty years ago to address the same problem, as was Title VII of the 1964 Civil Rights Act, which prevented sex discrimination. Were all those pieces of legislation also ineffective? What's going on here?'
