It was not public information that was released.  It was secret democrat information that was capable of influencing public opinion.  If the Russians released it, I am glad they did.  The release of true information can never undermine a US election.  In fact, even the release of false information by foreign governments cannot undermine a US election.  The underlying premise of a democracy is that voters are smart enough to make informed decisions and  are capable of sorting out and evaluating information available to them.  As long as we are dealing only with the release of information, elections cannot be undermined (unless you believe that the underlying tenants of democracy are flawed).  It is a foregone and reasonable conclusion that entities will release information favorable to their interests.  This is normal and healthy.  The crime is not undermining our election, it is merely phishing, which exists only through the stupidity of the phish.
