T Rowe Price, perhaps. I've been happy with them over the years. But make sure that they aren't in the same boat as Fidelity also.
BTW, Fidelity handles the 401K program for the government entity known as TVA. That's a big outfit. It would be interesting if Fidelity were to lose such a large number of customers.
Come to think of it, I’ll have to re-read the Hatch act. Fidelity, as the handler of the 401K program of at least one large federal agency, might be subject to the rules regarding political activity as outlined in the hatch act.
