Rep. George Miller (D- Ca.) introduced the Employee Free Choice Act in the House in 2007. As noted before, EFCA substantially dispenses with secret-ballot union elections supervised by the National Labor Relations Board. Instead, EFCA directs the NLRB to certify a union if 50% + 1 of the employees in a bargaining unit sign union authorization cards.

In 2001, however, Rep. Miller had a different position on secret-ballot union elections. In a letter to Mexican officials following a labor dispute in that country, Rep. Miller stated as follows:

However, we feel that the private ballot is absolutely necessary in order to ensure workers are not intimidated into voting for a union they may otherwise not choose.

Joining Miller as signatories to the letter were Barney Frank, Dennis Kucinich, Bernie Sanders, Zoe Lofgren, and Barbara Lee, among others. Each supports EFCA.
