Why not put it on the ballot and find out? Just because something put into a bill does not necessarily mean that it has the support of the people. It may have support of some people, just like ultra-radical evironmental wacko bills have support of the ultra-radical evironmental wackos, the handle that they are, but not the support of the people as a majority.
Because they have legislators to do that for them. That's their job. That's our form of government, not a pure democracy.
