All indications show that this is absolutely terrible for republicans' self interest, and popularity. trump has gone from winning the popular vote ~~(over 50% voted for him)~~ (a plurality of 49.8% voted for him) to polling at the 30%s. The recent 2025 elections (an off-year, so a variety of smaller elections at the state / city level mostly) have shown democrats are absolutely performing much better right now. This is not contested by either party.

> Is there some way aside from the obvious mistruths they can demonstrate its the democrats fault, and achieve some electoral advantage?

You discount the skill republicans have at lying -- regardless, when people are feeling the pinch in their pockets, they will blame whoever is in power. Currently it is the republicans.
