The GOP-led House just approved a six-month extension of the transportation law. After about 45 minutes of debate, the chair called for a voice vote, and no one objected. In this way, a unanimous consent vote might be even easier to pass than a vote under "suspended rules" which require a two-thirds margin, because in this case, all members were not called back to the chamber to vote. The only people voting were the ones in the chamber at the time.
Of course, any member who was determined to oppose the bill could have made sure to be in the chamber. But if every member of the House had been called to vote on the measure, it would have been more likely to have at least one dissenter.
