If Florida doesn't count, why hold a primary at all and waste people's time voting?  It's hard enough to improve voter turnout levels without telling them they're wasting their time.  Clinton is entitled to feel aggrieved at losing a lot of delegates and a lot of momentum because of an internal party spat that as far as I know, she had no part in.  Also, its not an attempt to change the rules, as I see it, simply an attempt to rescue some momentum from an otherwise entirely ruined opportunity to gain the upper hand.  

If the DNC move had been seen to disadvantage a progressive anti-establishment candidate, all the "progressives" would have been shouting conspiracy and bloody murder at the scandalous gerrymandering and hijacking of the nomination process by the DNC.  But because its works out against Clinton, that's ok then?
