Republicans, if they follow the guidelines in their Commitment to America, will restore energy independence that in of itself will great help bring down inflation.
They will competently manage the supply chains that will further help to bring down inflation.
They will close the border and do what they can to send as many illegals as possible home which will save the U.S. taxpayers mega billions and greatly help with getting escalating crime under control.
They will support the police, push back on these ridiculous defund the police campaigns and policies that make it almost impossible for police to do their jobs and push to start putting victim rights ahead of criminal rights.
They will stop emasculating the military
They will hopefully stop insane government spending that only helps those in government retain their power and/or pays off pet constituencies and that is a driving force behind much of runaway inflation.
They will re-establish the USA as a force to be reckoned with and that bad actors around the world will respect and choose not to provoke.
Most of this they can't accomplish until they re-elect President Trump or somebody like him with the instinct, vision, and skill set to get it all done. But for now they can at least stop the insane legislation that exacerbates the bleeding.
