Let's just take a look at the Lincoln Project's largest donors. From $25,000 on up. https://www.fec.gov/data/receipts/?data_type=processed&committee_id=C00725820&min_amount=25%2C000
One of the biggest donors is a group named "Majority Forward." This seems to be a relatively new group with only 7 preliminary FEC filings. Deep dives invited. https://www.fec.gov/data/filings/?data_type=efiling&committee_id=C90016098
The top dollar donor appears to be Ashton Media LLC, with a PO box in Ashton MD. Deep dives invited here, too.
"SMP" gave $550,000. I dunno who they are, but they have the same address as "Majority Forward," and Majority Forward is SMP's largest donor. And, MAN are they rolling in money!!! https://www.fec.gov/data/receipts/?cycle=2020&data_type=processed&committee_id=C00484642&two_year_transaction_period=2020&min_amount=1%2C000%2C000&line_number=F3X-11AI
Remember when Dems and Libs used to complain about all the "money in politics"? It's different now, ain't it? https://twitter.com/smc12256/status/1356055197924134915
I believe this may be correct. Although Perkin$ Coie more commonly uses Suite 800 in its address, there are examples of Suite 600 as well.

Ain't that special? The Lincoln Project's major sources of funding, SMP and Majority Forward share an office address with this guy ... Marc Elias!
I dunno if the Rs have any political law firms even half as effective as the Dems have. But if they don’t like losing they should find some pretty darn quick.
Hat tip to @MarkHyman for spotting the shared address. 
I should add that "SMP," which gave so much money to the Lincoln Project, and which shares an address with Perkins Coie's DC office, stands for "Senate Majority PAC." That's right, Mitch, the Lincoln Project was in on getting you fired. Not just Trump. https://www.senatemajority.com/about/
If there was any doubt about the Lincoln Project being outright sellouts to the Dems (and not just anti-Trump), consider that they spent 1.3 million bucks campaigning against Susan Collins. That’s right. Susan Collins.
Wow. The Lincoln Project sure throws a lot of money to one of its founder’s company. https://docquery.fec.gov/cgi-bin/forms/C00725820/1422761/se
The Lincoln Project paid another company belonging to one of its founders 1.5 million dollars in December, which then returned the money a few weeks later. What was THAT all about, I wonder??? 
Hmmm
