Americans’ opinion of congressional honesty has improved over the last year, but lawmakers are still more distrusted than even used car salesmen, according to a poll released Monday.

More than half of Americans — 54 percent — have a low or very low opinion of congressional honesty and ethics, Gallup found. That’s improved from 2011, when 64 percent had a low or very low opinion. Ten percent of high or very high opinion of congressional trustworthiness, up from 7 percent a year ago.
