Key Point: Yet Johnson has not yet taken the nuclear option: cutting ties with Trump. A few of his fellow Republican senators have done so, including Sen. Mark Kirk of Illinois who, like Johnson, is up for re-election this year.

Instead Johnson has suggested he might campaign with Trump, joking it could be billed as "The Ronald and the Donald."

Wisconsin State Journal: As Donald Trump plunges in poll, Ron Johnson campaign says he's 'running his own race'

Democratic U.S. Senate candidate Russ Feingold is working anew to link his Republican opponent, Sen. Ron Johnson, to GOP presidential nominee Donald Trump, who plummeted in the latest Wisconsin poll.

Johnson, meanwhile, seeks to preserve the delicate balance he has tried to strike with his party's controversial White House nominee.

The latest Marquette Law School Poll, released this week, showed Democratic nominee Hillary Clinton nearly tripling her lead over Trump among likely voters in Wisconsin, to a 52 percent to 37 percent advantage. Among registered voters, Clinton's lead was 46-36.

Feingold's campaign, which has consistently highlighted points on which Trump and Johnson agree, sought to further capitalize this week on Trump's recent polling nosedive. The campaign promoted a video with clips of Johnson praising Trump -- including saying "on the big issues, I'm in total agreement with Mr. Trump" -- spliced with clips of Trump making some of his most controversial statements.

Johnson, the first-term senator from Oshkosh, has supported Trump while stopping short of endorsing him -- a distinction some have questioned -- and made clear when he disagrees with Trump's most incendiary statements.

"What's clear is Ron Johnson is an outsider running his own race," Johnson spokesman Brian Reisinger told the Wisconsin State Journal in response to the latest Marquette poll release.

Yet Johnson has not yet taken the nuclear option: cutting ties with Trump. A few of his fellow Republican senators have done so, including Sen. Mark Kirk of Illinois who, like Johnson, is up for re-election this year.

Instead Johnson has suggested he might campaign with Trump, joking it could be billed as "The Ronald and the Donald."

The latest Marquette poll was the first the school conducted after the parties' national conventions last month -- and after Trump drew rebukes from many in both parties for a string of highly charged statements, including a feud with the family of a Muslim family of a U.S. Army soldier who died in the Iraq War.

The poll also showed Feingold continuing to lead Johnson, 53-42. Among registered voters, Feingold led 49-43.
