And then there was Trump's claim that China is Libya's biggest oil customer and that the United States gets "no oil from Libya."
In truth, Kessler found, the United States does get a small share of Libya's oil -- only 3 percent -- but China is far from its "biggest customer."
The Department of Energy says Libya's biggest customers are Italy, which buys 28 percent of the civil war-torn country's oil, France at 15 percent, China at 11 percent and Germany and Spain at 10 percent each.
Then there were Trump's attacks on whether Obama's was born in the United States. Trump is claiming vindication now for elevating the issue in numerous interviews -- a tactic that catapulted him into the news and drew attention to his presidential ambitions -- clearly forcing Obama to produce his official birth certificate this week.
After three years of ignoring the issue, Obama signed a letter to Hawaii state officials Friday requesting a copy of his official birth certificate. It was delivered Tuesday night. But early on, Trump said he had hired investigators digging into the "birther" issue in Hawaii and, based on their reports, was convinced that the birth certificate didn't exist. Now that Obama has produced a copy, Trump is touting this as a big political achievement.
Trump certainly forced Obama's hand by lifting the issue beyond the second-tier attention it has received. But it's an issue among a relatively small segment of voters that he could have sidestepped, saying that it's not among the top concerns on most voters' minds.
But worse than Trump's tendency to make things up are his off-the-cuff, sometimes bombastic comments about how he would handle major issues like the budget deficit, skyrocketing oil prices, and the threat of China.
On Libya, he would invade, presumably with the military, get rid of Moammar Gadhafi and seize the oil fields, if the Saudis would pay us the $5 billion it would cost, plus a cut in their oil supplies. On overall oil prices, he would call up Arab OPEC leaders and tell them "you've had your fun, but it's over." This bellicose talk is a frightening prospect for a country still embroiled in two wars and now dealing with the situation in Libya.
China is a hot-button issue for candidates to expound upon when they lack a domestic economic plan to boost growth and jobs. China is not responsible for our weak, jobless economy, excessive tax levels and unprecedented $14.3 trillion debt. Obama's failed, anti-growth economic policies are to blame.
Trump's shallow, sound bite-based campaign, which invents "facts" to fit his own reality, his threats to the Arab world, his promises to bully China, and his bragging about how "easy" it is to fix the fiscal mess we're in, without the hint of a well-thought-out plan, may play with some voters.
But this is not a presidential contender who has serious answers to the critical economic and fiscal issues we now face. Obama's birth certificate will not create a single job.
