It was a sight conservatives have waited decades to see.

This week on the White House lawn, President Donald Trump was flanked by House Republicans in a ceremony marking a historic legislative achievement: the passage of the Tax Cuts and Jobs Act of 2017. The act is being heralded in many circles as the most conservative, pro-growth policy to emerge from Congress since President Ronald Reagan’s 1986 tax reform.

One might think the name of the act alone would clearly resonate with the American people. (Then again, when you have legislative catastrophes named the “Affordable Care Act,” folks can be forgiven for some cynicism.) What could be better than keeping more of our hard-earned money and giving businesses the ability to invest in our nation’s economy, hire more workers and raise wages?

Apparently, not everyone is on board. In fact, most people don’t believe it.

How did this happen? How could the House Republican leadership and even the president allow such a momentous occasion to be summarily dismissed by the very people who will benefit?

Republicans have historically lost the public relations battle to Democrats and their mainstream media accessories, and while yesterday’s ceremony is a step in the right direction, one senses that average, hard-working Americans still want a common-sense explanation for how this tax bill will put more money in their pockets. This should have been done in the weeks leading up to the vote, but once again Republicans failed to control the debate.

Investor’s Business Daily reports that the tax plan is “widely unpopular” or “wildly unpopular” or “horribly unpopular,” depending on which news outlet one reads. The polling analysts at FiveThirtyEight say the tax plan is “historically unpopular,” noting that it gets an average of just 33% support in nine surveys taken in December, with 52% saying they oppose it.“ Yes, that’s the same FiveThirtyEight that had Hillary Clinton beating Donald Trump late into the evening on election night. Nonetheless, someone is shaping the public’s perception about this bill, and it’s not Republicans on Capitol Hill.

Most of the surveys asked very broad questions about whether Americans support the plan or whether they think they’ll receive any benefits. It’s no wonder that many respondents are suspicious about the legislation. After all, Democrats demonized the act as soon as they got a whiff of it. While Republicans in the House and Senate were squabbling over the details, Democrats had effectively characterized the plan as another scheme to take from the poor and give to the rich. It’s a BIG Lie, but an effective one.

National Review’s Jibran Khan states, "The predictable result is that a false claim — Republicans are raising taxes on all but the very rich, full stop — has spread like wildfire across Twitter, and has been given added momentum by think tanks, verified accounts, and trending hashtags. This effort has certainly paid off. According to a recent New York Times poll, only a third of Americans believe that they will see their taxes go down in 2018. It should come as no surprise, then, that the bill’s extreme unpopularity is in line with historic tax rises, rather than tax cuts: The majority of people think it’s a hike.”

But it’s hard to run from the facts, and even The Washington Post had to admit that “8 in 10 Americans will pay lower taxes next year, according to the nonpartisan [insert hysterical laughter at that characterization] Tax Policy Center’s analysis of the final bill. Only 5 percent of people will pay more next year. Mostly, those are folks who earn six figures and own expensive houses in places with high local taxes, such as New York and California.” Yet the Post led the Leftmedia assault on the bill, and none of those outlets are backing down in their effort to mislead the American people.

Alexandra DeSanctis writes in National Review, “A couple of weeks ago, the NYT editorial board co-opted the Twitter account of its opinion page and spent an entire afternoon issuing tweets, urging readers to call their senators to protest the tax-reform bill. They even went so far as to include the office numbers for each senator, so readers could more easily petition their representatives. It was outright political lobbying, from an editorial board that has routinely denounced Citizens United and decried the supposed involvement of ‘dark money’ in U.S. politics.”

Clearly, Democrats and their media propaganda machine will go to any lengths to stop the Trump/Republican agenda.

Senate Minority Leader Chuck Schumer (D-NY) said that the legislation “will be an anchor to the ankles of every Republican running in 2018.” Really? If Democrats truly believed that the tax plan will backfire on Republicans, then why did they fight so hard to stop it? Sounds more like Democrats are fearful that Americans will forget all of the rhetoric when they see more money in their 2018 paychecks.

Even so, Republicans aren’t helping matters. They need to do more than sit around and wait for the truth to take hold.

The fact that a significant number of Americans think that one of the largest tax cuts in American history is actually a tax hike should put Republicans at all levels on notice that they need to do a better job of communicating their ideas. This is the only way to overcome the coordinated assault on a measure that will fatten nearly everyone’s wallet.

But this is the problem. Democrats have always circled the wagons and come up with catch phrases and slogans to drive their points home. They never shy away from making their case, even when their case is baseless. Many Americans still believe that Democrats are the party of the working class, and Republicans are fat cats. That’s because the Left has been in lockstep on message for decades.

It’s time for Republicans to defend their ideas without apology. For the first time since Reagan, we have a president willing to embrace a bold, conservative agenda — if only members of his own party would join him.

President Trump has never been afraid of winning, but it’s taken Republican leaders in Congress a full year to catch on.
