Legislators are basically doing triage, responding to perceived consensus. Kinda like a product manager. Think attention economy. There's 10,000s of bills filed every year. No one has the resources or bandwidth to handle that.

Any given legislator has 1 maybe 2 issues that they care about, for which they will advocate an agenda. The rest, they rely on what they're hearing.

Intuit's lobbying effectively drowns out alternative view points. Assuming that anyone anywhere is consistently advocating for something like free auto-filing.
