Donald Trump may be the current GOP front-runner, but primary rival Sen. Ted Cruz, R-Texas, seems to have what it takes to bring him down, talk radio host Rush Limbaugh said Friday.

“Of all the Republicans in the NBC/Wall Street Journal poll, while it acknowledges that Donald Trump is adding to his lead, there is one Republican, according to the people polled in their responses here, there’s one candidate who could beat Trump for the nomination, in the eyes of Republican primary voters, and that’s Ted Cruz,” he said on his radio program.
