Donald Trump in recent weeks had been advising President Barack Obama to produce his Hawaiian birth certificate to prove he had one. Truimp refused to let journalists force him into dropping the subject. Obama had been refusing to give in until April 27th when Obama blinked.
Trump recognized that a president cannot have the confidence of the people if he withholds information for no apparent reason. The document Obama released on the 27th doesn't contain any information that needed to be kept secret.
Trump's willingness to stand firm to force Obama to do what he should have done long ago demonstrates Trump's leadership ability. Trump is more likely to stand firm against foreign leaders than Obama who let European leaders con him into a foolish Libyan adventure that has raised gas prices.
Obama is an attorney and shouldn't have needed to be reminded that an attorney is most likely to win if he presents the best possible evidence to the court, or (as an elected official) to the voters.
During the last two years the failure to provide the long form birth certificate has been a major distraction which has created doubts about whether Obama was even qualified to be president. Obama has been oblivious to the fact that his unwillingness to release the document was hampering his presidency.
If Trump wants to continue an offensive against Obama, he should focus on Libya and ask what the real reason for American involvement is. Trump might also ask Obama how NATO plans to stabilize the situation if Qaddafi is forced out of office. Al Qaeda attempted take to advantage of the overthrow of Saddam Hussein to take over Iraq and can be expected to attempt to take over Libya is Qaddafi is forced out. Has Obama secretly promised U.S. troops to keep al Qaeda out of Libya?
