Super Tuesday Exit Poll Results: Who Is Voting for Donald Trump

Voters for Donald Trump today look a lot like those who supported him in previous contests, according to results from the NBC News Exit Poll. A majority of his voters have no college degree. In comparison, among those voting for other candidates, about four in 10 are not college graduates.

And Trump's voters are angry — half express anger with the way the government in Washington is working. Voters for other candidates are angry, too, but not as many — about four in 10.

Consistent with that anger, Trump's voters overwhelmingly want someone from outside the political establishment — more than eight in 10 among those who've voted in primaries today.

The immigration issue is not at the top of voters' list today — many more pick the economy, government spending or terrorism. But among those who do say immigration is their top concern, Trump does well. And, at least among those in states where we asked the question, his voters agree with him on his call for the deportation of undocumented immigrants. Nearly six in 10 of his voters support deportation, while fewer than four in 10 of those voting for other candidates think undocumented immigrants should be deported.

Almost one quarter of voters decided in the past few days, and someone other than Donald Trump was the beneficiary those votes.

This has been updated with final exit polling data.
