Steve's barking; Why Uncle Bernie Winning would be good for the Democratic party

Uncle Bernie needs new voters to win.
There is a good chance that these new voters would vote along party lines, voting for Democrats.
In order for Uncle Bernie to win there must be a huge turnout of new voters.
If the Democrats put up candidates in every congressional district, the house will (surprise, surprise)  turn around.
The Democratic party needs new blood,so if my thesis is right they need Bernie more then Hilary for Hilary would not bring in new voters.
