It would mean the Dems would have to have a 2/3rds majority in both houses.

No it doesn't. If Congress passes a law or sets a procedural rule that says a 2/3 majority is needed for a tax increase, raising taxes is now a two-step process: Congress votes to change the law or rule to a simple majority, and then Congress votes to increase the tax with a simple majority. Neither one requires a 2/3 majority. Only a constitutional amendment requiring a 2/3 majority would do that.

Congress can’t just change a law. Read your Constitution.
