All these proclamations people are making about what will happen in the general election based on what has happened in the primaries are showing this is their first or maybe second election.
The energy and whole environment just radically shifts come general election time, you can't predict shyt. Not to mention how often things change during general election time itself before election day.
So, just chill with any hysterics about "this is why the Democrats are going to lose OMG!". TBH, candidates can tear each other apart during the primaries and to a certain extent it might not be THAT damaging during the general or even better, dealing with the dirt during the primaries gets out in front of issues. Imagine if Obama had to deal with the Reverend Wright shyt in October instead of March or April when he ended up giving a huge speech about the issue and buried it.
