For example,
1. Trump suspending H1B visas is him working on protecting American jobs. Democrats resisted that.
2. Tariffs on nations where manufacturing was pulled from the US.
3. The 2017 tax bill that made delaying paying taxes on overseas investments.
4. Perhaps most importantly of all, blue collar and union workers are the most skeptical of vaccinations with the lowest vax rates. In their view, its untrustworthy corporations that are pushing questionable vaccines on their workers. Democrats are clearly taking the corporate side and stand against the workers on this one, while the GOP is using this as a wedge issue to pry blue collar and union workers away from the democratic party. And this is a big issue on this front.
