I looked at this list and it is not actually accurate, let me tell you why..............
1) Eliminate oil and gas tax loopholes
(He did not break this promise, he threatened them to lower their prices or he would eliminate them, the oil companies complied which is one of the reasons we have the lowest gas prices in over 20 years.)
2) Expand child and dependent care credit
(Congress blocked him on doing this so the blame belongs to them, not on Obama breaking this promise)
4) Close loopholes in the corporate tax deductibility of CEO pay
(Another one that Congress has blocked him on doing, so again Congress to blame)
5) Create a foreclosure prevention fund for homeowners
(Again Congress)
7) Create a mortgage interest tax credit for non-itemizers
(Again Congress blocked, and between this one and #5 he asked the states to work out credits for homeowners)
8) Require automatic enrollment in 401k plans
(This one was approved back in 2012 however the stipulation was that they had to automatically enroll their employees in a 401k plan if they did not offer their own retirement plan)
9) Create a retirement savings credit for low incomes
(He is still trying to do this one, but once again Congress is fighting him on it and is one of many they have refused to vote on)
10) End income tax to seniors making less then $50,000 a year
(Congress blocking also, you really think Congress will agree with any tax breaks on middle to low income)
I skipped 3 and 6 because I have not looked into them yet, and as for the rest on that list most of them can be chalked up as Congress blocking or part of the many bills they have refused to vote on......
