These are the venues, caterers, and hotels the campaign paidfor events — the money trail to where fundraising happened, with the vendor's city and state. It is not a guest list or attendance: who came, who hosted, and “what the crowd was like” aren't in any public record, so we don't guess at them.
Categories are grouped by keyword from the free-text purpose each campaign reports to the FEC, so the split is a guide, not an audit. Otheris spending whose reported purpose didn't clearly fit a category — campaigns describe disbursements inconsistently. Totals are for the candidate's campaign committees this cycle; see the FEC for the line-by-line record.
