No sign anywhere that he's been slipping off to Hawaii this week, so I'd say the answer is no.
Incredible, just a few days after his grandmother's death and he's cracking jokes about seances with the dead, ridiculing 85 year old widow Nancy Reagan, etc. The death of his grandmother obviously didn't arouse any sense of respect for the aged, the recently deceased, or people in mourning.
People do grieve in very different ways but I have to wonder whether Obama ever cared at all for his dead white granny. Everything points to him being the kind of narcissistic egomaniac who thinks everyone else is simply there for his benefit and convenience.
If you think The One is a narcissistic egomaniac now, wait until he actually goes from being President Elect to President! He doesn’t have the power yet.
He went to sign off on cutting life support on November 2nd. That's why he said "I don't know if she makes it to the election," as if he were reciting some sort of play by play. He has odd "tells" in his speech, when lying about his family.
Re grandma’s funeral -— I heard on MSM news that the whole family will go to Hawaii for a vacation at the time there will be some memorial service or other for granny. Guess that will be this month or December. Wouldn’t want to waste a trip to Hawaii JUST for the service, now, would we?
