political fundraiser
A social event held to raise funds for a political candidate, party, or cause. Often involves a dinner or reception with a ticket price.
I plan to attend a political fundraiser for a local legislator next week.
Tickets for the political fundraiser were 20,000 yen each.
Compound of 政治 (politics) and パーティー (party), a wasei-eigo term for a fundraising event.
