The is a pretty comprehensive and factual pile of info that the GOP had all along, including Bernie's very thin resume. When he was 40 years old he became the mayor of Burlington and became a Senator. Before that, not much.
After that, still not much. You may not like the source, and you may not like the spin on it, but this information would have been used mercilessly, and would have ended up with a trump landslide.
I was not planning to jump on any more 2016 Election Trains, but this one caught my eye.
