As President, I would hate to go to all these things. I can’t stand Obama but the guy gets a ton of invitations and can’t go to everything. How many anniversary things do we have. He has to go to the 50th Anniversary of JFK Assassination in November so maybe that is the conflict. That is way more important as a President died that day 50 years ago.
Lincoln: Republican
Kennedy: Democrat
That’s all you need to know to understand Obongo’s decision.
He could easily attend both events should he choose to do so. They are several days apart.
