If you are campaigning for president and explicitly lie about a topic publicly and you win the presidency you should be impeached and possibly removed from office. CMV

So, for example, lets say President A said "I will lower unemployment to below 6% by November of next year." If the President does this, then it is all fine and dandy. However, if he does not he should be impeached. The senate should then decide if he is worth of being removed from office. I think this would work because it would force the President A to state how he is going to get unemployment below 6%, instead of just saying blatant lies. It would also add some transparency to the President and U.S. Government, instead of everything being "hush-hush." I agree, some things have got to be kept quiet but blatant lies should be punishable.

The president doesn't just get to "do" things he wants to or promised. He can influence legislation but as far as the actual drafting and passing of bills that's all about Congress. He can strive to change tax rates but at the end of the day what he can and cannot accomplish is hugely tied up  with the other two branches of government (for good reason) and so it would be unreasonable to base his job security on things outside his control.

Most candidates, at least successful ones, do lay out plans they'd follow to carry out their campaign promises. Unfortunately they need everyone on board to actually carry out the plan which rarely happens.
