咋最后这句话我看不出来有主语啊?

咋最后这句话我看不出来有主语啊?
全文如下,但最后这句reported显然不是主语,还劳烦各位大神帮我找找主语
A recent poll found that over 80 percent of the residents of Nalmed Province
favored a massive expansion of the commuter rail system as a means of
significantly easing congestion on the province’s highways and were willing to
help pay for the expansion through an increase in their taxes.Nevertheless,the
poll results indicate that expansion of the rail system,if successfully
completed,would be unlikely to achieve its goal of easing congestion,（就后面这句没主语吧）：because most of people in favor of expanding the rail system reported less congestion
during their highway commute as the primary benefit they would experience.
错了错了，我想说没找到谓语，不好意思了，谓语谓语
