WASHINGTON — Gov. Bobby Jindal announced Wednesday on Twitter that, as expected, he is running for president.

The Louisiana governor is the 13th Republican to officially enter the race and has spent months traveling across the country to build support for his campaign.

Jindal will kick off his campaign at an event Wednesday afternoon in New Orleans.

Jindal, a policy wonk, has already created a conservative policy group, America Next, to release his positions on energy, health care, foreign policy and other topics.

He is considered a long shot and trails far behind the top-tier GOP candidates in most national polls.

Albert Samuels, a political scientist at Southern University in Baton Rouge, said Jindal “has no chance.”

“He is somewhere between zero and 1% (in polls),” Samuels said. “Bobby Jindal will not get in the (presidential) debate.”

Fox News, sponsor of the first debate in August, has said participation will be limited to candidates in the top 10 of an average of national polls. The network will hold a separate forum earlier in the day for candidates who do not qualify.

Jindal is more popular in early primary states such as Iowa and New Hampshire than he is back home.

Joshua Stockley, a political scientist at the University of Louisiana in Monroe, said Jindal’s low approval ratings in Louisiana “could come back to haunt him, nationally.”

Jindal has said his pre-announcement visits to Washington and other places around the country haven’t affected his leadership in Louisiana.

“I’ve been to places in Louisiana where people have said, ‘You’re the first governor we’ve ever seen in my parish,'” he said recently. “That was important for me. I don’t think you can do the job sitting behind a desk, and I haven’t.”

Jindal, 44, whose term as governor expires in January, once was considered a rising star in the Republican Party. He was the nation’s first Indian American governor, and during the 2008 presidential campaign he was discussed as a possible running mate for the GOP nominee, Sen. John McCain.

He’s logged an impressive list of accomplishments. A graduate of Brown University, he was a Rhodes Scholar and served as his state’s secretary of Health and Hospitals and as president of the Louisiana University System. He’s a former chairman of the Republican Governors Association.

He represented Louisiana’s 1st Congressional District in the House of Representatives from 2005 to 2008, after serving as assistant secretary at the U.S. Health and Human Services Department during the George W. Bush administration.

Jindal also was executive director of the National Bipartisan Commission on the Future of Medicare in 1998.

On the road, he has touted his conservative credentials, including his opposition to abortion and to legalizing same-sex marriage.

He’s bashed President Obama on the Affordable Care Act and education — particularly on Common Core State Standards, which Jindal once supported.

Jindal recently said Obama hasn’t done enough to fight radical Islamic terrorism and has shown himself “incapable of being our commander in chief.”
