Support is TBD. As the story stated, "Republicans control Congress but they are split on some core tax issues. They’re in agreement on wanting to cut tax rates and simplify the byzantine tax system but they’re divided over whether to add to the government’s ballooning debt with tax cuts." (Strange how the deficit doesn't have the same urgency when the GOP is in control.)

The only way the Dems get onboard is if the tax break is actually for the middle class. Call me skeptical, but I'd be surprised if when the details come out, a majority of the tax cuts will go to the wealthy.
