Democrat wastes $62 MILLION of his own money on failed bid for Maryland Senate seat... so does it ever pay off to self-fund your own campaign?

Democratic Maryland Rep. David Trone wasted $62 million of his own fortune on a failed bid for his party's U.S. Senate nomination.

Trone was on Maryland's Democratic primary ballot Tuesday against Angela Alsobrooks, a county executive of Prince George's County, which cradles Washington, D.C. 

Alsobrooks spent around $6 million on the race - a 10th of what Trone did - and was beating the three-term congressman by about 12 points with 66 percent of the vote counted.

Trone founded and co-owns Total Wine & More and in October 2023 was estimated to be worth $2.4 billion, according to the Bloomberg Billionaires Index. 

The Washington Post reported Tuesday that Trone's $62 million run that Trone spend more of his own money on the Democratic Senate primary - to replace the retiring Democratic Sen. Ben Cardin - than any candidate in the 21st century.

Nort Dakota Gov. Doug Burgum, who - with other GOP politicians - appeared Tuesday at former President Donald Trump's hush money trial, holds the distinction of paying the most per vote of any modern candidate: $28,000 per voter

Trone spent slightly less than the $66 million former President Donald Trump put in to his longshot 2016 presidential campaign.

The real estate developer and reality TV star poured his own millions into the race against Democrat Hillary Clinton - while taking donations from donors and supporters as well - and pulled off a shock victory an election night. 

Since then, Trump has used donor dollars instead of his own case to run unsuccessfully for reelection in 2020 and to take back the White House in 2024. 

One of the candidates vying to be Trump's VP, North Dakota Gov. Doug Burgum, holds the honor of the candidate who has spent the most cash per vote. 

Burgum spent about $14 milion of his software and technology fortume on his 2024 presidential campaign. 

Since he dropped out before the Iowa caucuses, it means that his 500 or so votes cost $28,000 per voter, The Post said. 

Former New York City Mayor Michael Bloomberg spent an eye-popping $1 billion on his short-lived 2020 presidential campaign - where he dropped out and endorsed and then put his financial support behind Biden. 

Former New York City Mayor Michael Bloomberg spent $1 million to run for president in 2020, only to drop out and endorse President Joe Biden. Bloomberg won the American Samoa caucus and was on th ballot in many states, paying about $427 per vote

Since Bloomberg's name was on a number of primary ballots he spent about $427 per vote, The Post reported. 

He won just one race - the American Samoa Democratic caucus. 

Another Democratic on a quixotic run for the White House four years ago was Tom Steyer. 

He spent more than $340 million on a run where he received about 260,000 votes, getting each vote for about $1,315, according to The Post. 

Steyer campaigned heavily in South Carolina and is likely best known for performing Back that Azz Up alongside rapper Juvenile on the eve of the state's important first-in-the-south Democratic primary. 

But all that money only got him third place in the Palmetto State.
