obama's endorsement, does anyone really want to explain the 8 years of failure.That's won't help anyone against Trump. Obama won’t endorse anyone this early, he’ll do it when it’s down to about 3 presidential candidates left.  obama’s odds  of be correct will be a greater chance of not looking like a loser such as his presidency was.  With the great success President Trump is having, who would want a endorsement from a loser like obama or hillary.   If you want the uneducated voters you need his endorsement, but it comes with a “cost you have to be willing to except”.
