The "Additional Raised Since 3/22" column represents only contributions of $1,000 or more that were required to be reported via Form 497 prior to the election. McCann reported an additional $31,800.00 in these large contributions after March 22, followed by Chavez with $24,700.00, Aguirre with $19,100.00, and Moreno with $7,200.00. No large contributions were reported for Fuentes during this period.

It's important to note that complete financial information for the period after March 22 through the April 8 election is not yet available, as those filings have not yet been due. The current data represents only a partial picture of the final campaign finance landscape.

Party Committee Spending (Member Communications)

Political parties can spend money on candidates in the form of "member communications," which are filed as contributions via Form 497. Below are the reported party committee expenditures for the top two candidates.

Note: Some Form 497 filings report monetary contributions from parties to candidates. These have been excluded here, as such contributions (up to $35,200 under county rules) are already included in the candidate committees’ total contributions (in the above table) and would otherwise be double-counted.
