@McGentrix,
Actually, you may have missed my point. Bernie Sanders would create a very different election.
If Sanders were the nominee, the election would be about Socialism. We would have heard about Sanders alleged support for Venezuela, and Cuba ... and unfortunately there are videos of Sanders saying things that would make these attacks credible. Sanders is uniquely vulnerable to Trump's line of attack.
Sure, there will be attacks on Biden over his son and Ukraine. They won't be nearly as effective as the attacks on Sanders uncomfortable past comments on socialist leaders.
I am arguing that Biden, unlike Sanders, is the boring candidate. Instead of arguing over socialism, the election will be about Trump.
