Like online polls, all political platforms are crap.
They are marginally useful for getting an idea on the general thought processes of a candidate or a party, but the specifics rarely have anything to do with reality once elected.
Platforms are designed to mollify supporters and pressure groups, and create a gentle pink fog in the minds of voters onto which each one can project their own views.
Twenty years of consistent leftist political history counts for something. The fact that so damn much effort has gone into concealing that history from voters should have set off alarms in rational minds to start with.
There's a reason for the frantic encouragement to Democrats to vote early. There's only so many fingers that the media can shove into the information dike.
