The honest answer is that there isn’t much either party can do about inflation.
We have an imbalance between demand and supply due to the pandemic and Putin’s war. It’s a worldwide problem and all that can be done is to mitigate the pain. Democrats are trying to do that. Republicans can't even support supplying baby formula as a group.
The Republicans never have a plan to build anything good. Remember Obamacare? Republicans ranted and raved about how awful it was and how it would ruin the country, but when asked where their health care plan was, they never had one. They never came up with a single alternative.
Republicans legislate using fear. Whatever the Democrats want or do, they get out the fear machine, but when asked what they would do: it's nothing. No answers, no plan, no helpful contributions, nothing. Just more fear. That is the utterly useless Republican Party in a nutshell.
