To justify those reimbursements, Boebert would have had to drive 38,712 miles while campaigning, despite having no publicly advertised campaign events in March, April or July, and only one in May. Furthermore, because the reimbursements came in two payments — a modest $1,060 at the end of March and $21,200 on Nov. 11 — Boebert would have had to drive 36,870 miles in just over seven months between April 1 and Nov. 11 to justify the second payment.
