Jane Castor’s resounding victory over David Straz in Tuesday’s Tampa mayor election runoff was a high-priced affair, but Castor got far more bang for her buck — $300 per vote to be exact.

Straz spent nearly eight times as much per vote as his opponent in what turned out to be a rout.

The retired banker raised $5.1 million for his campaign — nearly all of it out of his own pocket — and spent $4.9 million through April 18, the period covered by the latest campaign filings.

That translates into $344.79 spent per vote for each of the 14,290 he netted in the runoff. Castor ended up with 38,854 votes, according to complete but unofficial results from the Hillsborough County Supervisor of Elections office.

By contrast, Castor spent $1,720,059 out of more than $2.1 million raised. Her per-vote average? Just $44.

Overall, Castor, Straz and the five candidates eliminated on March 5 dropped more than $7.3 million on the race to become Tampa’s next mayor.

Spending in the Tampa mayor’s race more than doubled the amount spent on the then-record-breaking 2017 contest in St. Petersburg between Rick Kriseman and Rick Baker.

And the stirrings of who might replace the term-limited Kriseman have already begun. The early squabble between Kriseman and probable candidate Darden Rice? Whether it’s too early to start raising money.
