Can you dispute the FACT that Trump had a campaign promise of a very tall wall across the southern border of the USA and that "Mexico will pay for the wall?"

Can you dispute that Mexico said they will not pay for the wall? Can you dispute that Trump is demanding billions of US money to pay for a scaled back wall?

Can you dispute the fact that the uneducated lower class are the main force of Trump's base? Yes, older males also are part of the base but not the main force of it.
