Sanders did not say Hillary was unquallified...

4. Bernie just sent the message that he's not going to sit back and take it

Bernie was given many invitations to go after Hillary on her emails and did not do it. The only reason Hillary is attacking Bernie now is because his campaign won't go away and he has become a legitimate threat.

Hillary and her campaign have been trying to pretend that Bernie pointing out differences in their records and in their positions on important issues constitute "personal attacks", which is complete bullshit.

If they want to play dirty, there is a never ending supply of material to tar Hillary with, versus the manufactured garbage like Sandy Hook that Hillary is having to resort to attack Bernie. Bernie is telling them if they want to go down that road, that's their choice.
