If you want to invest in this stock market, you need to forget about Washington, Jim Cramer told his Mad Money viewers Thursday. After watching multiple failed attempts to repeal Obamacare, Cramer said, he has little faith that Congress will ever pass tax reform, which is why he's focused on the companies that don't need reforms to thrive.

Let's not forget that tax reforms were item No. 1 on Trump's agenda before Congress wasted almost an entire year on healthcare. Cramer said that while Trump cares about the stock market, almost no one in Congress does. The only winner from nine months of failed healthcare policy debate was insurance provider Centene (CNC) .

So why should investors now believe that tax reform is right around the corner? Cramer said he's a firm believer in economic advisor Gary Cohn, but those in Congress have zero credibility.

The current proposals put state and local tax deductions at risk, something that certainly won't fly in high tax states like California and New York. They also increase the lower tax rates, and while those increases are offset by some deductions, they will still make for awful headlines that will doom the plan before debates even begin.

Cramer reiterated that he's not paying any attention to Washington and is instead sticking with companies that don't need Washington's help to prosper, companies like Centene.

Over on Real Money, Cramer says he cares about things that move stocks, not for a few minutes or a few days, but those that have a genuine impact on the future of the worth of companies. Get his insights with a free trial subscription to Real Money.

Executive Decision: Thor Industries

For his "Executive Decision" segment, Cramer spoke with Bob Martin, president and CEO of Thor Industries (THO) , the RV and motor home maker with shares that popped 2.5% today after the company posted a monster 31-cents-a-share earnings beat on very strong sales.

Martin said that Thor's strength stems from more younger buyers entering the RV market for the first time. While boomers are still Thor's bread and butter, he said that Gen X and Gen Y buyers are more interested in RVs than ever and they're buying smaller, more affordable units and finding lots of new ways to use them.

RVs aren't just for camping anymore, Martin noted, as they're perfect for weekend getaways and tailgating at your favorite sporting events. Many people in the paths of the recent storms in Texas and Florida used their RVs to get out of harm's way.

Martin added that today's RVs are packed with electronics, including multiple TVs and smartphone apps to control just about every function.

Cramer said he's still a believer in the Thor story and would use any weakness to be a buyer.

Whither Wayfair?

Some stocks are just battlegrounds between the bull and the bears, Cramer told viewers, and few stocks are as divisive as online homegoods purveyor Wayfair (W) .

After trading sideways for much of 2016, shares of Wayfair had seemingly caught fire this year, racking up an 80% gain in just the past six months. But the bears regained the momentum this month, with shares plunging from $83 to just $69 in a matter of weeks. Nearly 28% of the Mayfair's outstanding shares are currently sold short.

Cramer said the bear case against Wayfair is nothing new. The bears cite, of course, Amazon (AMZN) , along with Wayfair's strategy of spending big to grow marketshare. Add to that a rash of insider selling and a recent report that called the company's cash flow an "illusion" and it's easy to see why the shorts are piling in.

Cramer said while he's not entirely buying the bear case against Wayfair, he'd stay away from the stock anyway. You never want to be in one of these battleground stocks, he concluded, there are easier ways to make money.

Executive Decision: Applied Materials

In his second "Executive Decision" segment, Cramer also sat down with Gary Dickerson, president and CEO of Applied Materials (AMAT) , a stock that popped 6% yesterday and another 3.6% today after the company's bullish analyst day.

Dickerson started off by saying that things have never been better at Applied Materials. He said semiconductors are becoming pervasive in our world and their value as a company in that world is increasing every year. No matter what product you're looking at, from TVs to smartphones, they're all made with Applied Materials.

Dickerson continued by saying that many investors have long memories for the boom-and-bust years of PCs, but in today's market, big data and artificial intelligence are driving high-performance computing that doesn't suffer from these cycles. Whether it's healthcare, transportation or entertainment, there's tremendous demand for different kinds of chips and more powerful chips.

Cramer told investors to own and not trade Applied Materials, a company which he said remains a great long-term story.

Lightning Round

In the Lightning Round, Cramer was bullish on DowDuPont (DWDP) , Apache (APA) , Anthem (ANTM) and Pfizer (PFE) .

Cramer was bearish on Continental Resources (CLR) .

No-Huddle Offense

In his "No Huddle Offense" segment, Cramer said it's a changed world, but unless you're in touch with those around you, you might not see it.

Cramer credited his wife for his recommendation of Lululemon Athletica (LULU) and his daughter's recent camping trip for his continued interest in Thor Industries. It was also his kids who turned him onto Apple (AAPL) , a stock which he still owns for his charitable trust, Action Alerts PLUS.

If he hadn't paid attention to his family, he may have missed all of these trends, Cramer concluded, which is why a good investor needs to always keep their minds open to new ideas.
