HAD THEY NEVER MET HIM?:

The push reflects a broader anxiety within the party about the electoral environment this fall. It also has practical implications for the GOP: The resources devoted to Cruz include money that could otherwise be used to oust vulnerable incumbent Democrats in red states like North Dakota, Indiana and Missouri.

With O'Rourke outraising Cruz more than 2 to 1 during the past quarter, right-leaning organizations have begun routing resources to the state. The anti-tax Club for Growth, which spent millions on Cruz during his 2012 Senate bid, has started a seven-figure advertising blitz aimed at tearing down the Democratic congressman. The organization has begun polling the race, and David McIntosh, the organization's president, recently traveled to Texas to meet with donors who could help fund the barrage. More than $1 million has been raised so far, people close to the group say.

A handful of other well-funded groups are considering joining the effort, including the Koch-backed Americans for Prosperity, the Mitch McConnell-aligned Senate Leadership Fund, the newly formed Senate Reform Fund, and Ending Spending, which in the past has been bankrolled by major GOP financiers including New York City investor Paul Singer. Some of the groups have been in touch with one another as they weigh their next moves and try to determine how much their help is needed.

"I think there will be a lot of money," said Doug Deason, a Dallas investor and prominent GOP giver who met with McIntosh.
