Note:
(a) Apparently 磚 implies an inferior product.
(b) Regarding 排綠. As opposed to polling the public, polling KMT members alone will ensure a KMT candidate who is a party stalwart, not a fence-sitter.

(3) 防磚?  It is a term used by Taiwan media; KMT itself does not use it.

Note:
(a) 中國國民黨中央提名審核委員會召集人郝龍斌 is also vice chairman 副主席 of KMT.
(b) 中央提名審核委員會 has to report its recommendation to 國民黨 中央常務委員會 (abbreviation: 中常會; equivalent to CCP's politburo standing committee), which convenes every Wednesday morning --to make a final decision.
