It is asserted here (time stamp 10:04) that
My opponent [referring to Maxine Waters] only passed 3 bills in Congress in 27 years.
Is this true and how does an average person like me verify this assertion (and others like it)?
In my own effort to answer this, I looked into votesmart.org and govtrack.us. At a very cursory glance, the assertion seems false as Waters voted on more than 3 bills that at least passed the House. But I'm not confident in my judgment as this is the first time I think about checking this kind of assertion.
I have no stake in the assertion being true or otherwise. In the interest of giving the assertion some benefit of doubt, however, is there an interpretation of the assertion that makes it true?
