My understanding is there only needs to be a Majority of 1 chamber to Bring this to a state vote.

Then your understanding needs to improve.

In the case of disagreement between the Houses, the certification of a slate of Electors by the State's governor prevails.

I've been reading the Electoral Control Act of 1887 for weeks, and I don't recommend it. It consists of paragraphs damn near a page long. Based on what I've read, this site comes close to explaining a very complicated business in a reasonably short space.

Here is info on Joint Session Challenges to Electoral Vote Returns :

"While the tellers announce the results, Members may object to the returns from any individual state as they are announced. Objections to individual state returns must be made in writing by at least one Member each of the Senate and House of Representatives. If an objection meets these requirements, the joint session recesses and the two houses separate and debate the question in their respective chambers fora maximum of two hours. The two houses then vote separately to accept or reject the objection. They then reassemble in joint session, and announce the results of their respective votes. An objection to a state's electoral vote must be approved by both houses in order for any contested votes to be excluded."

You might want to keep a bottle of aspirin, whiskey or both handy while reading this stuff. Anyway, the likelihood of both the senate and the house approving the exclusion of contested votes is slim and probably none.
