WASHINGTON-Democratic Party leaders are upping the pressure on Bernie Sanders to drop his presidential campaign, alarmed that his continued presence is undermining efforts to beat the presumptive Republican nominee, Donald Trump, and again win the White House.

"I don't think they think of the downside of this," said Sen. Dianne Feinstein, D-Calif., a supporter of front-runner Hillary Clinton and broker of the post-primary peace between Clinton and then-Illinois Sen. Barack Obama in 2008.

"It's actually harmful because she can't make that general-election pivot the way she should," Feinstein said. "Trump has made that pivot."

The new concerns come after Sanders' recent wins over Clinton in Indiana and West Virginia. While those victories have provided his supporters a fresh sense of momentum heading into next week's primaries in Kentucky and Oregon, they did almost nothing to help Sanders cut into Clinton's nearly insurmountable lead in the delegates who will decide their party's nomination.

Still Sanders soldiers on, frequently telling the thousands of supporters who attend his rallies that he still has a narrow path to the nomination.

"Please do not moan to me about Hillary Clinton's problems," Sanders said in a recent interview with MSNBC. "It is a steep hill to climb, but we're going to fight for every last vote."

Clinton, her aides and supporters have largely resisted calling on Sanders to drop out, noting that she fought her 2008 primary bid against Obama well into June. But now that Trump has locked up the Republican nomination, they fear the billionaire businessman is capitalizing on Sanders' decision to remain in the race by echoing his attacks and trying to appeal to the same independent, economically frustrated voters that back the Vermont senator.

"I would just hope that he would understand that we need to begin consolidating our vote sooner rather than later," said Rep. Steve Israel, D-N.Y., a Clinton backer and former chief of efforts to elect Democrats to the House. "Democrats cannot wait too long."

Though Clinton has for the past few weeks largely focused her rhetoric on Trump, campaign aides say the two-front effort hampers their ability to target both Sanders supporters and Republican-leaning independents that may be open to her candidacy.
