Enough to make leadership answer
Five disciplined members can refuse to let the caucus pretend nothing is wrong. They can force public questions around rules, committees, hearings, and must-pass votes.
Power Math
A lone member can be isolated. A bloc can bargain, expose, delay, force votes, shape hearings, and make leadership choose in public. That is the point of running candidates together around a shared Contract.
Five disciplined members can refuse to let the caucus pretend nothing is wrong. They can force public questions around rules, committees, hearings, and must-pass votes.
Ten members can act as a negotiating unit. They can tie support to public commitments and make the cost of ignoring working people visible.
Twenty members with a shared platform are no longer a collection of personalities. They are a governing faction with a public mandate.
A bloc this size can change what counts as serious inside the House: what gets hearings, what gets scored, what gets negotiated, and what gets exposed.
The Contract has to connect outside pressure to inside tools. The members have to coordinate before the vote, not explain themselves after it.
