I am taking a guess, but I think that the tax cut arguement might have merit. I am not sure of how the estate laws work exactly but perhaps: A person could use tax free exchanges to build up a large property inventory without paying any taxes on the wealth created. They then take out a mortgage to use the money tax free, thereby gaining use of some of the gained wealth without losing any to taxes. The interest is offset by income on the property and depreciation. At the time of death, the properties would be handed over to the heir, minus the taxation that had been avoided and any recapture of depreciation. Unless the properties are mortgaged to the max and the money taken out all spent, they have effectively avoided the entire taxation of years of appreciation on a property and at the same time have reaped tax benefits for years. The property would not, of course, had to ever been mortgaged, but I wanted to show how they get to use the money tax free in the short term and then pass it on tax free in the long run. Since most wealth is accumulated in real estate, most wealth could go untaxed.
Oh yeah, the new tribune also endorsed him.
