After a week that featured a spat with Gold Star parents, squabbles with other Republicans and a nosedive in the polls, Donald Trump is looking to flip the script and stay on message, trying to keep the focus on his Democratic rival Hillary Clinton.

The Republican nominee tried to do so Friday, focusing largely on Clinton (save for a brief discussion about a baby at his event Tuesday) during a rally in Des Moines. This comes ahead of a speech Monday before the Detroit Economic Club, where he plans to expand on his economic plan and blast Clinton and President Obama for their economic records.

However, Republicans are wary that he can keep the focus on her and keep the white noise to a minimum. Most notably, they're looking for him to keep his eyes on attracting voters, which he has been hemorrhaging according to recent national and state polls thanks to unforced errors over the past seven days.

"He has to switch the referendum from himself back onto to Hillary Clinton and to completely stay focused on the fact that she would be an extension of President Obama's failures in office," said Ron Bonjean, a GOP strategist. "Giving a speech at the Detroit Economic Club is a perfect venue to talk about the failures of the American economy and it places squarely the blame on President Obama and Hillary Clinton as being the status quo candidate."

"The general thematic is Donald Trump is supposed to be the candidate of change" Bonjean said. "Instead, Hillary Clinton is trying to change it into whether Donald Trump is sane or insane as a presidential candidate and that referendum needs to switch very quickly. He cannot afford to drop the ball again, or else that thematic will keep getting reinforced."

One potential problem for Trump is the lack of advertising his campaign has put forth thus far as a general election candidate. Since winning the Indiana primary, Trump's team hasn't spent anything on ads, while Clinton and her allied groups have been a constant presence on the airwaves in swing states, focusing more on the importance of free media.

"It's a double-edged sword," said Brett O'Donnell, who served as director of messaging for Sen. John McCain's presidential bid in 2008. "He's gotten the lion's share of free media, but what he forgets is that that's just a medium for him to reach his audience."

"He's got to look at them as the medium to talk to his audience, and when he does that, then he can be successful. But instead, he focuses on the press and that gets him into trouble," O'Donnell said, adding that "if he remembers that he's talking to voters and he's not trying to convince the press, I think that would go a long way."

One of Trump's main issues throughout the week was his continued back-and-forth with members of his own party, particularly House Speaker Paul Ryan and embattled GOP senators John McCain and Kelly Ayotte, who are up for re-election. Trump pointedly endorsed all three of them at a rally in Green Bay Friday night in an attempt to shore up party unity and show his renewed Clinton focus.

Republicans still worry Trump doesn't know when to say when.

"He has a problem closing his mouth after he's made his point," said Bonjean. "I mean, he can be creative with that message going after Hillary Clinton in only a way that Trump can pull off. But he cannot go off on tangents. He literally has to stop and focus himself on what's really important here — is it winning the election? Or is it settling scores within his own party, or going after Gold Star parents?"

Earlier Friday, campaign chairman Paul Manafort called the week an "improving" one for Trump despite his standing in the polls. But with only 94 days until election days, many continue to wonder if improvement will be enough to put him over the top after the past week.

"They just have to figure out where his attention is going to be, because if it keeps getting divided away from ... attacking Hillary Clinton, it's just a failed day," Bonjean added. "It's just another failure."
