Senate Bill No. 490 seeks to regulate online political donation platforms and limit automatically recurring contributions by amending existing campaign finance laws. The bill repeals and replaces subsection (b) of section 9-601a, introducing new definitions and exceptions for what constitutes a "contribution." Key insertions include stipulations on the cumulative value of donations, such as a maximum of $500 for food or beverages at a single event and $1,000 for events hosted by multiple individuals. The bill also outlines restrictions on advertising purchases related to fundraising events to ensure transparency and limit conflicts of interest.

Additionally, the bill modifies the definition of "expenditure" and clarifies conditions under which endorsements are classified. It allows endorsements from unopposed candidates to be excluded from expenditure calculations and permits certain communications from candidates in non-overlapping districts. The bill introduces a new category for voluntary payments made to online platforms for operational purposes, exempting them from campaign finance reporting requirements, provided they are in addition to actual contributions. It mandates that online platforms obtain affirmative consent from contributors for recurring donations, ensuring contributors are fully aware of their commitments. Overall, SB 490 aims to enhance transparency in campaign financing while accommodating modern fundraising methods.
