Donald Trump's favorability ratings have taken a nosedive as of late, but one voting bloc among which the Republican presidential candidate remains popular is America's vapers.

According to a survey released Thursday, the GOP front-runner is seen as the most "pro-vape candidate" among electronic cigarette users despite their overwhelming tendency to identify as Democrats.

Thirty-eight percent of vapers associate with the Democratic Party, compared to just 24 percent who identify themselves as Republicans. Furthermore, nearly one third of e-cigarette users support former secretary of state Hillary Clinton's presidential bid, while 24 percent back Trump.

Nevertheless, Trump's popularity spiked when e-cigarette users were asked which White House hopeful they consider the most "supportive" of vaping.

Thirty-six percent of respondents said the brash New York billionaire is the most vape-friendly, versus 28 percent who chose Clinton. Vermont Sen. Bernie Sanders followed at 18 percent, while Trump's Republican rivals Ted Cruz and John Kasich drew 12 percent and 6 percent, respectively.

"Trump is in favor of fewer government regulations in most areas and vapers are worried about e-cigarette regulations," Adam Kustin, vice president of marketing at the leading e-cigarette distributor V2, said in a statement.

"This might explain his support. Trump is also backed by California's Duncan Hunter, known as the 'vaping congressman,' which is a key endorsement in the e-cig community," Kustin added.

The survey of more than 600 adult vapers in the U.S. and their political affiliations was conducted March 14-25.
