TPM Reader LC asks the following and I’ll try to answer …

I’m loving your coverage of George Santos in NY-3, and I’m wondering: Why are we only hearing about all this now? Don’t political candidates do oppo research? Obviously none of that was done, not even a little bit, since George Santos’s entire identity would collapse in the face of a not particularly vigorous sneeze. My question for you or your readers who may know – who is normally responsible for making sure oppo research happens? Is that the candidates themselves (Robert Zimmerman in this case), or DNC/RNC.

The first thing I would say is that contrary to what some readers are telling me, this part of the story is hardly being ignored. It’s almost the first part of every discussion I hear about this. For some it’s a failure of the Democratic Party; for others it’s a failure of journalism, gutted local news and so forth. But I want to start on the question itself: who is responsible for making sure the oppo research happens?
