Trump ups pressure on Clinton, tightens screw of his own party

Donald Trump's foot is pressing hard on the campaign gas. He is intensifying pressure on Hillary Clinton and the Republican Party establishment, and seeking to ramp up votes in the final primaries.

With all opponents crushed, the presumptive GOP presidential nominee is doing the opposite of taking a breather in preparation for the grueling general election campaign.

He's treating the remaining primary campaign and states yet to vote as opportunities to tighten his stranglehold on media attention, and to build his case against Clinton, the almost-certain Democratic nominee, putting her on the defensive.

"It's about turning the corner and starting the fall campaign," Trump adviser Ed Brookover told the Washington Examiner this weekend. "You notice in his remarks now, it's more focused on Hillary Clinton. ... If you hear what the message is now, it's about November."

Clinton's rival, Vermont Sen. Bernie Sanders, has no real chance to catch her, and she has pivoted to attack Trump for his temperament, rhetoric and populism. Her campaign has started issuing press releases with news of a growing list of prominent Republicans who have publicly declared that they will never vote for Trump.
