Do you live in the US? Asking, because I seem to remember you wouldn't and if that's the case it's a bit precipitate to declare, whether Republicans and Democrats may or may not agree on the urgency of an issue, in my opinion. Even, if you do, you can only speak for the small part of that massive country, you live in and that part of published opinion you consumed.
Edit: on a side note although you didn't mention it, personally I'd say a party having supported a former president, who's now demanding to be reinstalled against ther constitution having the majority in the HOR is a much bigger threat to undermine the constituional democracy, in my opinion., although I'm talking from outside the US.
