>>And "vote their conscience" is a weasel phrase. They had a duty to tally the votes, a procedure to follow. Some of them didn't want to follow the procedure.
So are you neglecting the Electoral Count Act of 1887? If the law and procedure requires they must vote when a proper objection is raised, it is not against the law to vote as they see fit, aka vote freely. This is the generally accepted meaning of "voting their conscience", not vague or misleading and thus not a weaselly phrase.
Perhaps you should cite the Constitutional support for the premise that Congress must vote a particular way when a vote is taken in this case. Especially when actual law and rule allows for the particular question to be raised and put to a vote.
>>A republic is a form of democracy. Arguing semantics has no place in HN.
There is a distinction, as described in Federalists no. 10, Madison proposes that representatives are elected to protect us from the failings of democracy. It is my understanding this is the generally accepted distinction of why we don't vote directly or bind our Senators and Representatives to vote a particular way. I feel it is germane because it means the actions taken were consistent with the specific republican form of government in the USA and to imply they were un-democratic or a threat to democracy is to imply the government is a different form.
In other words there is nothing wrong or unlawful with contesting the electors the way they did. Their only risk in Congress is if Nancy Pelosi (or whomever is Speaker) can gin up a ⅔ majority of members present for a quorum and win a vote to expel the objectors. And of course that can be for any reason she pleases, just like the impeachment. Which is why we may interpret the stated reason as partisanship.
