Hillary's Losing Strategy

So, Hillary Clinton's latest strategy is to suck up/brown nose President Obama., especially through Twitter: https://twitter.com/HillaryClinton?ref_src=twsrc%5Egoogle%7Ctwcamp%5Eserp%7Ctwgr%5Eauthor
Of course, Obama loves it and will endorse her.
But right now, Obama's approval rating is about 48% and a 49 disapproval rating, according to Gallup.  http://www.gallup.com/poll/113980/gallup-daily-obama-job-approval.aspx
And there is no guarantee it will stay at that level, especially if the economy crashes and when the Republican president nominee will rip on Obama horribly, especially if the nominee is Donald Trump.
Since Hillary is already dissing a minimum of 49% of the U.S adult population and there is no guarantee that she will gain 100% of Obama supporters, this is going to be a losing strategy by Hillary.
