Dem aides could face massive layoffs

It happens to some degree in every election cycle.

But, most Congressional committee staff (as opposed to staff in a Congressmember's personal office) bring substantial knowledge of particularly policy issues to the table and generally find it fairly easy to find work in DC - with think tanks, public interests groups, trade associations, etc.

And not just as lobbyists. Two of the policy analysts in my organization were displaced Republican staffers from House/Senate Committees.
