Funding profile

Tammy Baldwin

Democrat · Senator from Wisconsin

Career totals · 4 elections · 20122030

$109 million

raised by Baldwin’s campaigns, everything from 2012 to 2030 added together.

7%

of it came from organized groups rather than from people giving on their own: at least $7.6 million from PACs, plus donations that organizations collected and directed.

$87.7 million

was spent about Baldwin by outside groups. These are ads for or against them that their campaign cannot control, and none of it is part of the money above.

Every number on this page comes from Federal Election Commission filings, read on August 24, 2026. An election still under way keeps raising money, so its figure will have grown since. Check Baldwin on FEC.gov

Where the money came from

Everything Baldwin’s campaigns have reported raising, split by who gave it.

Federal Election Commission filings across 4 elections. Percentages may not total 100 because each is rounded.

Money bundled through organizations

Not every “individual” donation arrives on its own. An organization can collect checks from its members, already earmarked for Baldwin, and deliver them in a bundle. The law counts that as individual money, but the organization still chose where it went.

$936,000

reached Baldwin this way, 1% of everything they raised from individuals. Each donation came from a real person. The organization picked who got it.

  • JStreetPAC$530,000
  • EMILY's ListA group that works to elect Democratic women who support abortion rights, and one of the oldest donation bundlers in politics.$406,000

We can only count the organizations we have measured, so the real figure could be higher than this, never lower. Bundling is legal and widely used, and appearing here is not evidence of wrongdoing.

Who gave the most

Committee contributions from the 2024 and 2026 election periods, grouped by how the FEC classifies each giver. This covers a slice of the career total, and giving to a campaign is legal and ordinary.

The FEC records that a committee is a corporation; it does not record its industry. Those labels are ours, kept in a published list anyone can check. Where we have not labeled a giver we say “Other” rather than guessing.

“Unclassified” means the FEC records no organization type for that committee, which usually means a leadership PAC. We show it as unclassified rather than guessing which industry it belongs to.

Money spent about this member

Outside groups, usually super PACs, may spend without limit on ads for or against a candidate, as long as they do not coordinate with the campaign. Baldwin has no legal control over any of it.

This is not a donation. Nobody gave this money to Baldwin. It was spent on advertising about Baldwin, and money spent against a candidate is plainly not funding them. So it never gets added to the figures above.

$87.7 million

has been spent for or against Baldwin by outside groups. $13.1 million supported Baldwin; $74.5 million opposed Baldwin.

Largest outside spenders

Summed across 4 elections, using the Commission's aggregated totals so amended filings and 24-hour notices are not double-counted.

Spent supporting

$0

Ads urging people to vote for this member. Still not their money, and they cannot direct how it is spent.

Nothing on file.

Spent opposing

$64.1 million

Ads urging people to vote against this member. This money was spent to defeat them.

Election by election

The career figures above are the sum of these elections. Each row links to the Commission’s page for that election, where the numbers match line for line.

ElectionRaisedFrom PACsOutside spending
2030in progress$2.8 million$127,000 5%$28,000
2024$59.6 million$3.1 million 5%$59.5 million
2018$31.5 million$2.4 million 7%$11.3 million
2012$15.1 million$1.1 million 7%$16.9 million

Raised is everything the campaign took in for that election. From PACs is the slice of it given by political action committees. Outside spending is what other groups spent on ads about the race, for and against—it is not part of “Raised”. An election marked in progress is still raising money, so its figures are not final.

We never publish the names of individual donors, and anything we cannot source stays off the page. The methodology explains every such choice.
