I am not a fan of either, but if I can understand why folks in a different financial situation would feel differently.
I would view the 2k as a tax rebate for being over taxed, personally. But others who don't pay as much taxes, it's just a gov't handout. I think Trump has to move away from this stuff and pay down the debt. Either way, he shouldn't say it until it's a go.
For the mortgage, it's hiding the growing problem of homes being too expensive for first time buyers. Only way it can benefit would be to take one, but pay principal down faster if you can. One of the big issues is contractors don't build starter homes much anymore, as it's not as lucrative.
