Trump has been making specific promises to voters at his campaign rallies, such as exempting tips from income tax to appeal to hospitality workers in Las Vegas. He has also pledged to put Libertarians in his cabinet to gain their support and promised to undo Biden's electric vehicle policies to appeal to autoworkers. Critics say Trump is pandering for votes and may not be able to deliver on some promises that require congressional approval. His shifting stances on issues like wind energy have drawn skepticism from some he is trying to court. Polls show Trump has made inroads with union households in Michigan, tightening the race there.
