The thing is republican's love to tout the spending of federal money for their states/districts which they voted against. how is biden suppose to counter that...
also, as someone pointed out where was the media coverage of Biden of announcing 16 Billion dollars in infrastructure spending in Delaware the other day. oh wait i'm being told it was more important to provide coverage of someone throwing yet another public tantrum in a courtroom, my bad
I'm not sure if the politics of spending and government awards work anymore. Wealth inequality and the sense that the system is rigged might have just undone it all.
If the Democrats really wanted that though, it would be smarter to direct spending to winnable states. Instead Democrats keep passing bills (like the IRA and IIJA) where the benefits go predominantely to red states and where they won't get credit no matter what they do. Trump did just the opposite; the bills that has pased going overwhelmingly to his base and targeted his oponents (SALT for example). It's for sure asymetrical. One side is trying to break government in order to take control of it.
I don't really know how Reagan was able to remain pupular despite high inflation, but even if wages were keeping up with inflation, it's just psychologically battering to go to the store and be shocked every time you get the bill. Probably because the economic experts liked his solution of tax cuts and rewards for business and so the narrative was that Regan was fighting it.
I don't think the Republicans really care about touting wins though. For them it's really about culture wars and big ticket issues. I don't think Biden is particularly good at appearing like he's going to the matt for a cause (even abortion). He might win as a result of not alienating anyone, but it's a hard way to ever have real popularity
