Yeah, love him or hate him you cannot deny he makes for excellent circus.
As far as the wiretapping thing goes, I did not take Trumps accusation to mean that Barack Obama, himself, personally, literally, walked into the basement of Trump Tower and using his own hands and technical skills placed a listening device on the analogue telecommunications lines leading to Trump's room. I honestly have not been following this issue very close, but I would give him a pass if it was the case that a government agency monitored his communications, and say it was an accurate statement if it was found that someone high up who was a major appointee (like Loretta Lynch for example) was involved in the decision. I am not saying this is the case, just laying out how my evaluation of the statement would be made. If it was found that a government agency did monitor Trump but the decision can be traced back to (for example) a Bush era appointee then I would say that is probably not something that cannot be blamed on Obama.
I also took his statement to be yet another ninja smoke bomb to distract from the last controversy. he just keeps throwing chum in the water whenever the media starts getting close to taking a nip out of him, and it's working.
