Read the poll, this still shows that Clinton has a larger slice of low income voters. Also who do you think Trump's base is? The people who voted for him given a pick at any of the potential nominees for president, or the people who had additional choices eliminated and were encouraged to vote based on partisan loyalty?

Also I've included polling data that is past the primary, and includes voter sentiment for the general election, such as the gallop poll. The trend towards upper-middle craftsmen jobs remains.
