Sununu now has a republican trifecta, he isn't going to be able to maintain his popularity anymore because they are almost certainly going to push some hardline culture war bullsh**t like defunding planned parenthodo or something that will alienate the populace. Sununu will then have to choose between vetoing it and pissing of his base(loosing the primary) or not and having his popularity erode.
I don't think he's favoured.
The GOP doesn't have the margins in legislative to really push any culture war stuff.
