About Obama's coattails:

Barack Obama thinks he has accomplished something with his endorsement of 81 Progressive Socialist primary candidates in a single . . .
multi-media event.  In 2014,  he charged the Dems with the extreme need to turn out at the polls.  No one listened,  and the Democrats suffered the most one sided midterm election in party history.  So much for Obama's coattails. 

Trump,  on the other hand,  had endorsed 10 candidates,  nine have won their primary elections.
