Americans, and not just Republicans, are beginning to realize that it's time to unite behind Ted Cruz if we want to beat Donald Trump. There's no guarantee Trump would lose a general election when a candidate like Hillary Clinton would face him, given that Clinton is just barely holding down a joke like Bernie Sanders.

So Ted Cruz is starting to pull in the big bucks he'll need to get there.

We're used to Hillary Clinton raising money from Wall Street. Big businesses love big government, and despite Hillary Clinton's support for changing the rules on carried interest, she raises many millions from hedge fund managers like George Soros.

But it's news when a small-government, anti-cronyist Republican like Ted Cruz is starting to raise from those fund managers too, pulling in millions for his allied PACs. People are starting to wake up to how terrible Donald Trump would be, and are realizing we must stop him by any means necessary.

Some will say "Oh, it's just paying him off for opposing carried interest changes," but again, Donald Trump and Hillary Clinton agree on that, and Clinton gets millions anyway. So when that argument gets floated, forget it. There's no evidence of that.

Investors know Donald Trump could lead to ruin, because his eccentric ways would lead to global chaos, and economic recession. They know his tax-and-spend plans, starting crazy "trade wars" would choke economic growth, because raising taxes and tariffs to foreign levels only hurts Americans, not other countries.

Wall Street is starting to realize that Trump's brand of big government would be so bad, even they would be hurt by it. So they're joining with Ted Cruz. He'll have the money to compete to the end.
