Alabama Republican U.S. Senate contender Tommy Tuberville’s campaign bus went up in flames on Tuesday night, as his campaign sputters amidst a heated competition with former Attorney General Jeff Sessions for the seat.

The DeKalb County Sheriff’s Office reported that Tuberville’s campaign bus burst into flames on Interstate 59 while heading northbound. The bus driver was not injured due to the massive fire.

Tuberville was once considered the favorite to beat Sessions, but his campaign is losing steam as the public realizes he is a RINO. President Donald Trump, who has publicly supported Tuberville over Sessions due to his controversial tenure in the administration, has even cancelled a planned Alabama rally in favor of Tuberville, perhaps sensing that he has backed a loser.

Polling from June shows that Sessions is surging against Tuberville, as Alabama voters realize which candidate is the genuine article. Sessions has a longstanding conservative voting record, particularly on the crucial issue of immigration, while Tuberville has no record other than being a mediocre college football coach.

Big League Politics has reported on Tuberville’s weakness as a candidate on the matter of immigration. He has supported flooding the U.S. with foreign labor to squeeze Americans out of well-paying jobs to boost corporate profits:

Football coach and Alabama Senate candidate Tommy Tuberville appeared to endorse the notion of admitting 400,000 Indian visa workers to the United States in remarks made on an Alabama politics podcast in December, claiming that current rates of illegal immigration are the only factor stopping the country from bringing in the large pool of workers.

“We have 400,000 people in India that are educated, well trained… That want to come here. They want to be Americans, they want to get into our system, they can help. 400,000, we can’t let them in, because we’re being overrun by illegal immigration.

IWe need workers, there’s no doubt about that. We need workers to come the right way.”

The use of the H1B program to replace American workers with Indian tech professionals is well documented, and it’s doubtless that allowing 400,000 workers from the world’s second most populous nation to immigrate to America on the premise of their supposed workplace skills would prove devastating to many American tech professionals.

American IT companies are increasingly staffing themselves with a workforce primarily made up of Indian nationals, pushing American workers out of the workforce in exchange for a staff that will work for far lower wages. The H1B program tethers visa workers to their employers, creating what is essentially a system of indentured servitude, where quitting a job jeopardizes a visa worker’s green card prospects.

As seen during recent elections in Virginia, Colorado and North Carolina, voters are realizing that Trump does not necessarily endorse the best and most conservative candidate for office. This trend of voters rejecting Trump’s picks may continue in Alabama on July 14 during the GOP runoff primary election for U.S. Senate.
