Obama did not spend the entire election talking about Hillary being bought and paid for, rather he talked about what he was going to do. Hillary was critical of him, big time, but not really the other way around. I would say Obama pedestal was still on him during his inauguration day (both of them) so you may have a point.
Are you getting confused about who won in 2008? At this time in 2008 it was Obama who had sewn up the nomination
. Bernie in 2016 is in the same place that Hillary was in 2008 (and Hillary 2016 is playing the role of Obama in 2008).
At this time in 2008 Hillary was still taking shots at Obama. She was still attacking Obama for Reverend Wright (Obama's former problematic pastor) and she published an attack ad that included an image of Osama Bin Ladin. Since there was no realistic way for Hillary to gain the nomination, Obama supporters were calling for Hillary to drop out and were quite upset that she was still attacking Obama.
Read the article again... it was Hillary in 2008 who was accused of risking the Democrats chance of winning the White House by continuing her campaign beyond the point it was mathematically feasible for her to win.
If Hillary is as gracious towards Bernie in 2016 as Obama was towards Hillary in 2008, it will go a long way toward unifying the party and winning the White House.
How quickly Hillary supporters have forgotten.
