Fuming Republicans have also flooded the page with one-star reviews, bringing Behemoth's average down from five stars to three in less than a day.

"The whole thing is just surreal," owner Andrew Childs told Newshub.

"We couldn't have orchestrated it if we tried."

The brewery originally brought out 'Dump the Trump' before the US election in 2016 - partly as a joke, partly as a warning.

"Obviously it didn't work," says Mr Childs.

Realising the joke wasn't terribly funny after President Trump became a reality, Behemoth shelved the beer until earlier this year.

With the wave of scandals rocking the White House and the Robert Mueller investigation heating up, Mr Childs thought now would be the perfect time to bring it back.

"We thought he'd be impeached by now," he admits.

He's none the wiser as to how so many people found out about 'Dump the Trump', but assumes someone with a large online following must have shared their post.

"It just takes one person for something to spread."

He initially thought the reviews and comments might have been "Russian hackers" due to their sheer volume, but most of the profiles seem to be legitimate.
