No, using illegal tactics is not permissible or necessary. It is illegal and it is a violation of the oath.
We can return this nation to its constitutional roots by simply, and strictly following the constitution.
That is what we need...and if we elected people who were willing to do that, we would undo the harm relatively quickly.
What illegal tactics? The tactics aren't necessarily illegal, but tactics that ignore past traditions and things such as Senate rules and things that "push the envelope", but have not necessarily been declared illegal. And someone can pretend their actions are constitutional until someone proves them wrong./
It anything being done was clearly illegal, there would be some legal remedy. Some of it involves little more than pushing Republicans around who are too cowardly to fight back.
