According to the article, Likud has 130000 members who will be voting in primaries. For a party of such a size the 3000-strong Central Committee sounds megalomaniac, to have 1 Central Committee member for every 43 party members. I picked communist parties as the reference point simply because these were/are the largest parties known, and not as a veiled accusation of Likud having communist leanings. When a party with some 20 million members had a 500-something strong CC [like CPSU did] it sounded more proportional. Even its general congresses were only about 6000-strong affairs.
More, even if one was to take "central committee" in the case of CPSU extremely broadly and add to it every member of every subordinate territorial committee from the district level and up [Likud in all probability would not have such an elaborate structure if only due to the country size], even then the ratio of these officials to the general party membership was much smaller than 1:40 - it was on the order of 1:400 at most. Hence the megalomania diagnosis.

As a Likud member with a pretty good idea of how the party functions I must say your post shows amazing ignorance and makes assumptions not in evidence. The purpose of the Central Committee is to make major decisions for the party rather than having the party leader (currently Tzaki Hanegbi) or a few close advisors make such decisions on their own. The purpose of the Central Committee is to limit the size of referendums to make them manageable rather than open every little vote to the entire party membership. Again, the presence of the Committee insures a greater voice for more disparate views and greater democracy within the party. American parties would benefit from such a structure.
