Robert Max Ross

Treen was elected to the United States House of Representatives representing greater New Orleans the next year, the first Republican to represent Louisiana in Congress since Hamilton D. Coleman left office from Louisiana's 2nd congressional district in 1891.

Ross was born in Baskin in Franklin Parish to Robert States Ross and the former Ruby Seymour (1911-2002), and resided in Mangham in neighboring Richland Parish.

Robert Max Ross (August 5, 1933 – September 15, 2009) was a Republican activist and a candidate for numerous statewide and local offices who resided in Mangham in northeastern Louisiana.

He was among the earliest advocates for the Republican political movement at a time when no GOP candidate had been elected statewide in more than a century.

Ross was defeated by fellow Republican Ross Patrick Shirah (born August 6, 1940), then from Monroe, in the intra-party challenge to Passman.

Passman was first elected in 1946, and had previously never faced a Republican challenger on the general election ballot.

In 1956, he obtained a Bachelor of Science degree, with a major in agriculture, from Louisiana State University in Baton Rouge.

He was a 1962 graduate of the United States Air Force's Squadron Officer School at Maxwell Air Force Base in Montgomery, Alabama.

He was decorated with the Bronze Star Medal at McChord Air Force Base for services while engaged in military operations against the Viet Cong in 1962.

Treen, had run unsuccessfully for the United States House of Representatives from suburban New Orleans in 1962, 1964, and 1968.

in the gubernatorial primary, Treen carried the support of the party leadership, including GOP chairman Charles deGravelles, of Lafayette, while Ross was the "outsider."

At the time 98.6 percent of state voters still registered as a Democrat.

Ross was publicly critical of the leaders of the Louisiana Republican Party, and vowed to continue his fight for open elections within the party, as opposed to nominees being chosen by those in leadership.

Ross also publicly criticized Treen by noting Treen had once been a Democrat, whereas Ross had been a lifelong Republican.

Nonetheless, with party leaders heavily backing Treen, as well as support from President Richard Nixon and Governor Ronald Reagan of California, Ross stopped active campaigning for the nomination but did not officially remove his name from the ballot.

Louisiana has only had one contested Republican gubernatorial primary in its electoral history, the election of 1971–1972.

Republicans did not usually appear on the ballot in previous elections dating back to Reconstruction.

When qualifying ended in August 1971, eighteen Democrats had qualified, and only two Republicans, Ross and Dave Treen, then a lawyer from Metairie in Jefferson Parish.

On Saturday, November 6, 1971, Treen defeated Ross overwhelmingly, 9,732 votes (92 percent) and 839 )8 percent) for Ross.

He ran as one of two candidates in the Republican primaries for governor in 1972 and Louisiana's 5th congressional district seat in 1974.

Ross announced his campaign for the 1972 gubernatorial election in February 1971, the first announced Republican to enter the race.

Treen would go on to lose to Democrat Edwin Edwards in the general election held on February 1, 1972, but Republicans had their best showing in more than a century, as Treen polled 42.8 percent of the vote and carried many parishes in North Louisiana.

Despite Ross' poor showing, he and Treen remain the only Republicans to ever participate in a closed Republican gubernatorial statewide primary in Louisiana.

In 1972, Louisiana had not elected a Republican to the Louisiana State Senate throughout the entire 20th century.

Ross received more than five thousand votes in the general election but was still soundly defeated by Brown.

When Ross first qualified to run for any political office in 1974, Louisiana had been a one-party state for more than a century.

Less than 1 percent of the state's voters were registered as Republicans.

Following the end of Reconstruction, the Democratic Party had served as the only party to elect officials to public office at nearly every level of government except for U.S. President.

In 1974, Ross qualified as a candidate for the Republican congressional primary as a challenger to longtime U.S. Representative Otto Passman, in Louisiana's 5th congressional district.

In 1974, there were fewer than 5,000 Republicans registered in the 5th District of Louisiana but more than 216,000 Democrats.

Shirah eventually dropped out, and Passman was re-elected by default.

Republicans did not field a candidate in the election of 1975, and the new Louisiana Constitution of 1974 eliminated closed primary elections, creating the current jungle primary for future elections.

Despite having also been a candidate for governor, Ross additionally filed as a Republican candidate for the Louisiana State Senate seat held by veteran Democratic incumbent Charles M. Brown, of Tallulah, Louisiana.

In 1975, Ross qualified as the lone Republican candidate for the Louisiana State Senate in District 33.

With the adoption of Louisiana's new jungle primary, Ross did not advance to the runoff.

After Louisiana adopted the jungle primary system, Ross qualified again for governor in 1983 and also the United States Senate in 1984.

He additionally ran for the Louisiana State Senate as well as mayor of Mangham during other election years.

In 1983, he filed for the nonpartisan blanket primary for governor and polled a minuscule 7,625 ballots.

The other Republican candidate that year was David Treen, by then the embattled incumbent governor, who failed in his bid for a second term.

Treen received 588,508 ballots (36.9 percent), but the easy winner was the Democratic choice, former Governor Edwin Edwards, with 1,006,561 votes (63.1 percent).
