Cruz cozies up to Trump, aims for his supporters

As other Republican presidential candidates go after Donald Trump, Texas Sen. Ted Cruz is getting cozy with him.

The two men are in a so-far cordial competition for many of the same anti-establishment conservatives, and they're about to share a stage.

On Wednesday, at Cruz's invitation, Trump is to appear with him at a Capitol Hill rally protesting the proposed nuclear agreement with Iran.

One of 16 GOP candidates looking up at Trump in the polls, Cruz says the invitation was only to attract more attention to the "catastrophic" deal.

Yet Cruz needs the same frustrated voters who have pushed Trump to a polling lead five months before primary voting. If it takes a shared stage to convince those conservatives that he should be their choice, so be it.
