• Effective campaigns spend more time getting votes than money.

    Well, you can use money to buy outreach. Which can bring in more votes. So they are connected.

    One of the reasons Biden dropped out was because donors had decided to withhold money from his campaign.

    no one watches cable so ad buys are cheap.

    I imagine it’s more popular in certain parts of the US (e.g. the midwest). In particular where we need to pull never trumper votes away.

    Spam texts/emails are essentially free,

    Texts cost money. Emails are not free either if you are doing it with a high enough volume. See https://sendpulse.com/knowledge-base/email-service/general/how-much-bulk-email-costs for a comparison. (This is because it costs the underlying ISP some money to deal with the traffic involved.)

    Internet/social media ads are also dirt cheap…

    The ultimate problem is, even if they are cheap, if one side has more money than the other, then that side can outspend the other on ads, meaning they get larger outreach, potentially more influence (tho money doesn’t always buy influence - who wants to take the risk), and so on.

    I legitimately don’t even know how this much money is even spent,

    Actual campaign funds have to be reported regarding spending, you can view that info over at https://www.fec.gov/data/browse-data/

    This stuff is generally opaque and hard to understand, but a good “rule-of-thumb” kind of guide to it is available at https://www.propublica.org/article/how-to-understand-political-contributions-campaign-finance

    This is not a good thing.

    Agreed.
