an elliptical clause

Explanation:

An elliptical clause is a clause which can be a dependent or subordinate clause in which a word or words have been missing. The part of the clause which is missing is either a verb or a verb phrase. At times, it creates confusion to the readers and the writers especially when the sentence ends with a pronoun.  In the above sentence, the clause 'as much as them' is the elliptical clause in which the word 'like' is missing.
