The voting public is offered a choice, vote for this guy, or that guy.
They are not asked, "name somebody you wish to have represent you in office."
Therefore, most of the time, we simply elect the (what we believe to be) lesser of the odorous.
I do not see the politicians' character faults being laid at the feet of the voter.
Sure you do, the MSM do it all the time when it’s a Republican.
