Trump's early lead in Louisiana, according to CBS News Elections Director Anthony Salvanto, was the result of the candidate faring much better in absentee ballots cast. Election day voters, however, showed softening support for Trump later in the evening.

He thanked the states of Louisiana and Kentucky and dismissed his second-place finish to rival Ted Cruz in both Maine and Kansas. Trump said his campaign barely spent any time in those states, estimating that it was "two hours in one place and two and a half hours in the other."
Of Cruz's win in Maine, Trump added: "He should do well in Maine, because, let's face it: It's very close to Canada."
