Because the Billionaires that fund them are too bat shit crazy to ever get elected. Scott Walker(and others) sugar daddy, David Koch once ran for president in 1980 and received a whopping 1% of the vote.
Koch was the Libertarian Party’s vice-presidential candidate in the 1980 presidential election, sharing the party ticket with presidential candidate Ed Clark. The Clark–Koch ticket promising to abolish Social Security, the Federal Reserve Board, welfare, minimum-wage laws, corporate taxes, all price supports and subsidies for agriculture and business, and U.S. Federal agencies including the SEC, EPA, ICC, FTC, OSHA, FBI, CIA, and DOE. The ticket proposed legalization of prostitution, recreational drugs, and suicide. The ticket received 921,128 votes, 1.06% of the total nationwide vote.
They are too looney and extreme to run on their own so instead they buy politicians to run for them. They can purchase an experienced politician, get them elected then get their way much better than attempting to run themselves. While there are many versions of this, here is a shining example.
Wisconsin born billionaire Foster Friess, has taken a look at the field and decided to purchase a rick santorum. While one would think that Rick Santorum is crazy enough, you would be wrong, he can be trumped with even crazier.
FRIESS: On this contraceptive thing, my gosh, it’s so inexpensive. You know, back in my days, they used Baer Aspirin for contraceptives. The gals put it between their knees and it wasn’t that costly.
and they say unions are the problem?
