The mechanism. Washington doesn't need to write a check to Detroit or Silicon Valley to move money — it just has to decide who's eligible to bid. Two separate but reinforcing rules do that in fleet electrification: (1) domestic-content preferences under the Build America, Buy America Act and DOT/FHWA's Buy America rule for EV chargers, which the administration is now proposing to raise from a 55% domestic-component floor toward 100%; and (2) cooperative and federal purchasing vehicles (GSA Schedules, Sourcewell contracts, state fleet awards) that require vendors to already hold a qualifying, U.S.-assembled product line. Neither rule mentions a company by name. Both quietly reshape who wins the RFP.

Who cashes in.
