Name another woman who started campaigning for President in 2013. In fact, name another person from either major party who actively campaigned in either 2008 or 2012 and who started building a serious platform for a 2016 run before Hillary.
The point is, Hillary didn’t just come out of nowhere, and if people wanted to challenge her the time to start doing it was right after Obama’s second inauguration. Biden didn’t do that. Bush didn’t do that. No other woman did. This election has pretty much always been Hillary’s to lose, and nobody stepped forward with an offer of an alternative when it could have made a difference.
