Not that it matters now - But if Clinton did not have his Super PAC dumping millions of dollars in ads in crucial states, these things would then matter.
It's practically over & Clinton sits on like 100M money from her corporate masters (read - Super Pacs)
Clinton's Super PAC has barely spent anything on the primary. Meanwhile, between Sanders astronomical ad spending (not sure why his supporters are okay with him redistributing so much money from poor college kids to ad agencies and media corporations...) and the millions of dollars in pro-Sanders/anti-Clinton Super PAC spending he's benefiting from, he's outspent her in most states.
