Obama took 92 golf trips during his first term at an expense of about $35 million. So far, after just over 6 months, Trump has taken 41 golf trips and has cost the tax payers over $58 million. He's actually cost us 65% more than Obama's entire first term in his first six months. The projection, if he lasts 4 years and golfs at this rate, is that he'll take 307 golf trips and cost US tax payers over $440 million. That's almost $3.50 a second!
