Cracked dropout
Can this be fixed? If so, how?

Three options: First straighten everything and weld it back together. But caveates are the weld may break down the brass in the tubes that hold it in place between the stays. Second is to un-braze the drop out and replace it with a new one. Both will involve repainting the area repaired. In many cases more $ than it is worth to replace the frame as the third option.

You can easily fix a small crack in a steel frame but this is not a crack it's a break in an important area and the welding most people can do won't be enough.
If you have taken some welding classes and have access to an arc welder you could fix it but it won't be 100% unless you put a new dropout on there as Mad Honk suggests and it seems doubtful it's worth the time, money and effort unless it's a very expensive frame.

Gosh another gloom and doom reply with no context or deeper explanation. At least you do follow up with a more detailed reply that I do agree with.
Drop out replacement is a very real option. Whether it's the value the OP will choose is the real question. Yes a weld would secure this, and if done well perhaps for a long time. But these dropouts crack from a few reasons that welding won't fix. Like being over heated during the frame's brazing. There are many builders who have replaced the drop outs many times because of this kind of crack. Campy drop outs seem to be a common brand to see this. But then they are one of the more common brands too so a larger population. Andy

Andy,
No doom and gloom here but there are problems with what I see to repair this drop out. A wire welder won't adequately repair the dropout, and would need a stick welder to fix it but the heat would be detrimental to the brazed joint at the chain/sear stay. As I said earlier this repair could be done with correct procedures in place. but will be costly. Smiles, MH

The proper welding process for repairing this is TIG. If done correctly, there will be minimal paint loss and no damage to the brass attaching it to the stay. That said, it won't fix the design flaw that allowed it to break in the first place.

A competent welder could repair that as well as add a small reinforcing plate across the opening.
Good picture too!
