On Election Night, jubilant Democrats celebrated Barack Obama’s victory at the Driskill Hotel in Austin, Texas, including a woman who attended a similar party there 44 years earlier — for her father.

Obama’s victory, Luci Johnson Turpin said, fulfilled one of Lyndon Johnson’s greatest dreams. “Daddy and the members of Congress and the great civil rights leaders worked desperately hard to open the doors of opportunity for social justice,” the former president’s younger daughter said. “It was Barack Obama who walked through those doors.”

Older sister Lynda Johnson Robb called the outcome “very exciting,” especially since the other Democratic finalist was Hillary Clinton.

“To have the last two Democratic candidates be a woman and an African-American — I think Daddy would have been very pleased,” she said. “And it was wonderful it happened in the year of his 100th birthday.”

Since Obama’s election, the Rev. Martin Luther King Jr. and other civil rights leaders have received deserved credit for helping break the presidential color barrier.

But no one is more deserving than Lyndon Johnson, the Hill Country native who became the 36th president and presided over a civil rights revolution, yet no one seems to get less credit.

At the Democratic National Convention in Denver, a video marking Johnson’s 100th birthday had such an obscure slot it wasn’t mentioned on the daily press schedule.

Obama cast himself in his acceptance speech as an heir to Franklin Roosevelt and John Kennedy, praising Bill Clinton’s presidency but never mentioning LBJ.

“Lyndon Johnson has been kind of the invisible president, and that saddens me,” Luci said.

She blamed the continuing cloud of the Vietnam War, an event “which broke a nation’s heart but none more than Lyndon Johnson’s.”

“He saw the impact it had on his dreams of achievements in terms of domestic progress,” Luci added, citing such landmark measures as Medicare, Medicaid, anti-pollution measures and federal education aid.

“Maybe it’s because so many things like Medicare and Head Start have been so successful that we forget where they came from,” Lynda said.

Expansion of civil rights remains one of their father’s most enduring achievements.

He championed the civil rights revolution his predecessor only reluctantly embraced. And LBJ shepherded and signed three major rights measures that reshaped the society of his day and the electorate of the future.

Guarantees of nondiscrimination in public facilities, education and employment made the 1964 measure the most far-reaching rights measure of modern times. The 1965 Voting Rights Act expanded the electorate and made possible Obama’s election.

Ironically, LBJ correctly predicted short-term damage to his Democratic Party.

“I think we delivered the South to the Republican Party for your lifetime and mine,” he told aide Bill Moyers after signing the 1964 bill.

Even before that, Republicans were using opposition to civil rights to woo the South from its century-long Democratic home.

A generation later, white Southerners remain one of the electorate’s most Republican elements. This year, the biggest GOP majorities among white voters were in six Southern states, including Texas.

But an ever-expanding black turnout enabled Democratic percentages to rise in eight of 11 one-time Confederate states. Obama carried three — Virginia, North Carolina and Florida — and surpassed 45 percent in two others, Georgia and South Carolina.

On the night her father signed the 1964 act, coincidentally her 17th birthday, Luci Turpin recalls him telling her, “As a result of the courageous act of this Congress, many men and women who have stood up for this bill and helped it to become law will not be returning here just because of their courageous act.

“And many men and women will be coming to Congress who otherwise would not be able to get here because of the courage of this Congress.”

Now, one of them will occupy the office Lyndon Johnson once held, and he is a major reason.
