Donald Trump continues not to release his tax forms, which makes any in-depth analysis of his giving rate and charitable gifts impossible. He maintains he has given $100 million to charity in his lifetime, but that number can't be tracked or verified at this time.
Ted Cruz's tax return for 2014 shows that his and his wife's adjusted gross income for 2014 was just over $1.2 million. However, there is no mention of charitable gifts. Between 2006 and 2010, the couple donated less than 1 percent of their combined income to charity.
Hillary and Bill Clinton had an adjust gross income of just under $28 million in 2014. They donated $3 million to charity, at a giving rate of 10.8 percent. Most of their charitable giving went to the Clinton Foundation, which focuses on global issues of economic development, climate change, girls and women, and global health.
Bernie Sanders and his wife, Jane O'Meara Sanders, had an adjusted gross income of $205,000 dollars in 2014. They donated $10,367 to charity, or about 5 percent of their income.
