GOP pollster says voters have 'investigation fatigue'

Republican pollster B.J. Martino told Hill.TV's "What America's Thinking" on Friday that voters may be fatigued from special counsel Robert MuellerRobert (Bob) Swan MuellerFox's Cavuto roasts Trump over criticism of network Mueller report fades from political conversation Trump calls for probe of Obama book deal MORE's probe into Russian interference in the 2016 presidential election, which wrapped up last week.

Martino weighed in as members of Congress push for the release of Mueller's report, which he filed in confidential form to Attorney General William BarrWilliam Pelham BarrSupreme Court comes to Trump's aid on immigration Words matter, except to Democrats, when it involves impeaching Trump Justice OIG completes probe on FBI surveillance of ex-Trump campaign aide MORE last Friday. The Justice Department has faced mounting pressure to release more details about Mueller's findings.

"I think voters have investigation fatigue now, though, on both sides," Martino, a partner at the Tarrance Group, told host Jamal Simmons.

"They do want to see the full report, absolutely," he said. "Do they want investigations in Congress? Do they want impeachment? They're clearly saying no." 

"They do want to return back to issues," he added.

Barr told Congress in a four-page written summary on Sunday that Mueller did not find enough evidence to conclude that Trump's campaign conspired with Russia to interfere in the 2016 election.

Trump and his allies say the findings exonerate the president, but lawmakers — especially Democrats — are demanding the complete release of Mueller's findings, which are believed to be hundreds of pages long.

Lawmakers point to Mueller's apparent lack of a conclusion as to whether Trump obstructed justice by interfering with the probe itself, saying the full report could shed light on his decision.

Martino on Friday noted that Trump has continued to dwell on the 22-month Russia probe and the officials behind it, while his administration this week has also backed a legal challenge seeking to toss out ObamaCare.

"Now the president has some vengeance he would like to inflict upon those who came after him, and he decided he wanted to go after health care," Martino said. 

"I think that's a two-prong approach that's stabbing himself in the foot in both prongs," he said. "We would rather see a focus back on those issues that we know Republicans can win on, those economic concerns. Talk about the economy. Get back to those issues where we've had some success, and continue to grow that."
