Why is there such a disconnect between congressional approval rating and re-election rate?
According to a Gallup poll, Congressional approval rating is at a mere 20% (it use to be much lower in the past years) as of Sept. 2016. <http://www.gallup.com/poll/1600/congress-public.aspx> Yet, in the US senate, there's a: > 90% re-election rating in the House > > 96% re-election rate in the Senate. <http://www.gallup.com/poll/1600/congress-public.aspx> What might be a reason for such a big disconnect? If the people do not approve, why are they electing the same people? Is it do to the lack of knowledge voters have about the candidates?
