Released Tuesday, the polling data reveal mushrooming voter disillusionment with incumbent Republicans.
Conducted November 9 and 12, the national telephone and online survey asked 1,000 likely U.S. voters: "Thinking about next year's elections — suppose that your vote determined which political party controls the U.S. Senate. Would you vote for the Republican Party or the Democratic Party?"
In all, 48 percent of respondents said they would vote for Democratic candidates, versus 42 percent opting for Republicans.
For Establishment Republicans, the poll is the just latest harbinger of trouble.
On November 7, Democrats swept elections in Virginia and New Jersey, thrashing Establishment Republican challengers in every major contest.
These victories snapped a year-long losing streak for Democrats and left the party hungry for more.
They may get it. Other indicators suggest that if currents trends hold, the Democrats may reconquer Congress in the 2018 mid-terms.
A week before Republicans were trounced in Virginia and New Jersey, Rasmussen published new findings showing that despite constant excoriation in the press, President Trump is preferred over Republican leaders in the U.S. Senate.
A majority (57 percent) of likely GOP voters said the Republican Party should follow the president's vision for the country, versus 33 percent who preferred Establishment Republicans like Senate Majority Leader Mitch McConnell of Kentucky.
Of those who "strongly approve" of the president's job performance, 87 percent said the party should become more like him.
Additionally, 50 percent of those surveyed believe the country benefits when the commander in chief criticizes Republican senators for refusing or failing to advance his agenda.
As a whole, voters regard GOP senators as a greater roadblock for Trump than Democrats.
In all, 67 percent of Republicans say their own senators "have lost touch with the party's base," while just 19 percent grade the Republican-controlled Senate "good or excellent."
For some establishment Republicans, the handwriting has long been on the wall. In October, Senator Jeff Flake of Arizona announced he would not seek reelection at the end of his term. Flake cited the "coarseness of our national dialogue" for his decision to bow out; conservative analysts, on the other hand, suggested his 21 percent approval rating inspired the decision.
Flake's resignation followed a pledge in September by Bob Corker of Tennessee to exit the Senate once his term is up — a sign, suggested former White House strategist Steve Bannon, that the draining of the swamp is underway.
The polls and elections and stand-downs support Bannon's contention that "out of ideas, guts and money," the GOP Establishment is collapsing.
In October, the former White House chief strategist Steve Bannon declared war on incumbent, anti-Trump Republicans for refusing to support the president's reforms.
He painted the majority of congressional Republicans as obstructionist politicians beholden only to financial interests. In failing to defund Planned Parenthood, to repeal and replace Obamacare, to pass tax cuts, to reform the tax code and to pass an infrastructure bill, he said, they have impeded President Trump's agenda and must be purged from office.
The members of the "Establishment, globalist clique on Capitol Hill," Bannon declared, "have to go."
