The tax deduction for mortgage interest has long been popular for homeowners, but it's been limited to taxpayers to who itemize their deductions. In the 2008 campaign, Barack Obama promised to broaden the eligibility so non-itemizers could take advantage, too. Obama said he would pass a "universal mortgage credit" equal to 10 percent of mortgage interest for non-itemizers, up to a maximum credit of $800.

But four years later, it hasn't happened.

"I have not seen anything to suggest that that's been accomplished," said G. Barry Wilkinson, a longtime CPA and tax attorney in St. Petersburg, Fla.

The latest IRS literature on deducting mortgage interest, dated December 2011, spells out that only itemizers qualify. The IRS web page devoted to this topic has a headline for "Recent Developments," but there is a blank space underneath.

The Obama campaign couldn't provide us with any evidence this was fulfilled, but said Obama has pushed fairness principles in his 2013 budget.

But still, there's no mortgage interest credit for non-itemizers.
