President-elect Donald Trump’s senior adviser, Jason Miller, noted a change in the Republican Party‘s demographic, which was marked by the building up of the working class since winning Tuesday’s election.

As of Wednesday morning, Trump had garnered 277 electoral votes, with the counts still out. Three remaining states, Michigan, Arizona, and Nevada, are also leaning toward Trump. Miller predicted his boss could win as many as 312 votes during an appearance Wednesday on the Today show.
