For a decade, war widows in matching yellow suit jackets and hats quietly and persistently have knocked on Capitol Hill doors seeking an end to the "widows' tax," a government policy that deprives them of benefits from their husbands' military service.

They are always warmly received, but that's where the hospitality ends. Despite pledges of help from scores of federal officials - including President Barack Obama and House Speaker Nancy Pelosi - their long quest remains unfulfilled.

Every year since 2005, the Senate has voted to eliminate the policy that denies widows the ability to collect both a military survivor's benefit and the full annuity bought when their military husbands were alive. But in each of those years, the fix was dropped when House and Senate negotiators wrote the final bill in private.
