You can't take the politics out of politics. Of course the timing is suspect, and on average efforts to make changes like this don't succeed. But occasionally they do, and now is a good time to start talking about them. Forcing Republicans to take stances on things before November is an excellent idea, because the Republican party itself is in the process of crumbling, and depending on the outcome of the election, there is a chance to pass legislation on various issues that would make life better for the average American.

As you point out, the whole process is totally messed up, politics is so dirty, large corporations and the ultra wealthy are so powerful. But on occasion we do see positive change, so we shouldn't write it off as impossible or meaningless.
