This whole waste of taxpayer money is a result of projection.
The Democrats are accusing Trump and his cabinet of doing everything that they themselves do. They simply cannot imagine that any politician would NOT engage in cheating and dirty tricks. This is why they keep pushing the “investigation” even as it keeps floundering around, ever wider of its mark. Because they know that if *they* were under investigation, enough evidence would be uncovered to fill volumes, and they are incapable of believing that a Republican could actually be innocent.
