A primary win by "Ray" Moore would open Alabama's U.S. Senate seat to Democrats, President Donald Trump told radio-hosts "Rick and Bubba" this morning.

Trump called the popular syndicated radio show on Monday, just days after appearing at a Huntsville, Alabama rally for Republican Senate candidate Luther Strange.

"Luther Strange is going to be a great Senator," Trump said. "He loves Alabama, he loves the state and he loves the country. He will absolutely win against the Democrat. Ray will have a hard time. If Luther wins, the Democrats will hardly fight. If Ray wins (Democrats) will pour in $30 million."

When host Rick Burgess clarified that Moore's first name was Roy and not Ray, Trump came back with why it's "not a good sign" when the president doesn't know your name.

"I don't know that much about Roy Moore," Trump said, using the correct first name. "Roy Moore is going to have a very hard time getting elected against the Democrat. Against Luther, they won't even fight."

Strange, Alabama's former Attorney General, faces former State Supreme Court Chief Justice Moore in tomorrow's Republican primary. The winner will meet Democrat Doug Jones in the Dec. 12 election. Democrats are pushing to flip the seat to blue after long-time Alabama Senator Jeff Sessions was named U.S. Attorney General by Trump and Strange was appointed to the seat by ex-Alabama Gov. Robert Bentley.

During his Huntsville campaign stop, Trump promised to campaign for Moore should be victorious over Strange.

"I told Luther, and I have to say this, if his opponent wins, I'm going to be here campaigning like hell for him," Trump said.

The president is confident, however, Strange will hang on to the seat.

"I'm 5-0 in these races. I want to make it 6-0," Trump said Monday.

Correcting the president?

After the call, Burgess said he corrected the president after he called Moore the wrong name twice.

"If he had only said Ray one time I wouldn't have corrected him," Burgess said. "But when he said it twice, I had to say something."

"That may have been your best two-point turnaround in 24 years, when you have to correct the president," joked co-host Bill "Bubba" Bussey, who emceed the Friday night Trump rally.

Speaking about the interview, Burgess said the call was "like interviewing your uncle."

"He just says what he's thinking and that can be good or bad," he added.

According to Trump, the Alabama interview was his first radio appearance since he took office in January.
