支持B！

OG198：Although Napoleon's army entered Russia with far more supplies than for any previous campaign, it had provisions for only twenty-four days.

If than is followed by a clause referring to army, the subject of that clause must be singular (it). Furthermore, the verb of that clause will need to be in the past perfect form (had had) because it refers to a time before the simple past of entered.

用在本题：If than is followed by a clause referring to costs, the subject of that clause must be plural (they). Furthermore, the verb of that clause will need to be in the past perfect form (had accounted for) because it refers to a time before the simple past of accounted for.

由此可得选项B

也可推出B的than后省略的不是句子，而是一个名词，即the proportion。

其实than+句子的情况也可以看作定从省略了所修饰的名词，如：Although Napoleon's army entered Russia with far more supplies than (supplies) it had had for any previous campaign, it had provisions for only twenty-four days.

所以这道题我认为两种说法都对：

1。Soaring television costs accounted for more than half the spending in the presidential campaign of 1992, a greater proportion than (the proportion) they had accounted for in any previous election.

2。Soaring television costs accounted for more than half the spending in the presidential campaign of 1992, a greater proportion than in any previous election.
