If such election is made with respect to any bond described in clause (1) of the taxpayer, it shall also apply to all such bonds held by the taxpayer at the beginning of the first taxable year to which the election applies and to all such bonds thereafter acquired by him/her and shall be binding for all subsequent taxable years with respect to all such bonds of the taxpayer, unless, upon request by the taxpayer, the Secretary permits him/her, subject to such conditions as the Secretary deems necessary, to revoke such election.
