Republican pollster Conor Maguire said on Monday that policies explicitly attached to President Trump Donald John TrumpSteele Dossier sub-source was subject of FBI counterintelligence probe Pelosi slams Trump executive order on pre-existing conditions: It 'isn't worth the paper it's signed on' Trump 'no longer angry' at Romney because of Supreme Court stance MORE tend to lose support in surveys.

"We look at this all the time in polling. As soon as you attach that Trump name to it, you lose a huge percentage of voters right away in their support," Maguire, senior client strategist at WPA Intelligence, told Hill.TV's Joe Concha on "What America's Thinking."

"It is amazing. Whether it's just the 'I don't want to agree with anything that the president is pushing forward,' or 'I don't want to give him credit for anything,' that certainly plays a big role into it," he continued.

"That's kind of one of the things we always test, and always look at, [which] is why do people not like something? Is it strictly just party? Is it strictly anti-Trump? Or is there something more to it?" he said.

Maguire's comments come after a Fox News poll released last week showed that former President Obama's signature 2010 health-care law is currently more popular than the Republican tax plan, which was passed last year and supported by Trump.

Republican leaders and Trump have touted the tax law, saying it has contributed to economic growth and has aided small businesses and individuals.

However, the issue has not gained a significant amount of attention on the campaign trail ahead of November's midterm elections.
