Question

the bold word is a \middle swabi\ (subordinating conjunction). does the highlighted comma belong?
stuart the minion worked on his campaign speech,
after a long day of meeting the voters.
keep the comma
remove the comma

Explanation:

When a subordinating conjunction (here, "after") follows an independent clause and introduces a dependent clause that provides additional context for the main action, no comma is needed to separate them. The dependent clause "after a long day of meeting the voters" directly modifies the main clause's action, so the comma is unnecessary.

Answer:

Remove the Comma
