it gets more young votes. Real appeal.
there was a Democrat Party presidential candidate in the 2008 primaries who advocated 18 year drinking age, as he argued if you're old enough to go to war in the military, old enough to die for your country, then you're old enough to drink alcohol. While Obama and Hillary disagreed, although they had no actual factual response. I think it was Alaska's Senator Mike Gravel. He also ran for president in 1972 and 2020. fading into the lower tier candidates. He was called a "maverick" and even joined the Libertarian Party later in life, although not really sharing many Libertarian Party positions. But drinking at an early age was fairly libertarian. He also endorsed decriminalizing drugs, making them a public health issue rather than a crime. Libertarian again.
he was going to lose, so he was more honest. if you're in contention for winning, you lie more. candidates are like that. Got him some publicity too. "attention getter" is what critics called him.
Gravel served 3 years in the Army, as an officer during the Korean War. He had a clue what drinking meant to soldiers during war time. He was buried at Arlington National Cemetery. While the leading 2008 Democrat candidates, Barack & Hillary, had never served in the military. In 2020, he ran again, saying about leading candidate Biden "Is this the best the Democrat Party has to offer?" Biden also never served in the military and doesn't drink alcohol, at all.
