Mark Steyn said on "Hannity" tonight that people keep claiming Donald Trump's presidential campaign has a ceiling and can only go so far, but his poll numbers continue to show that's not true.

Steyn noted that a recent Fox News poll revealed that not only do 25 percent of people support Trump as their first choice, but 10 percent support him as their second choice.

He added that the poll shows Trump trailing Hillary Clinton in a head-to-head matchup 47-42 percent, which is significantly closer than just a few weeks ago.

"The Republican establishment needs to consider the fact that this guy is a serious leading candidate. He could well win the nomination and he has as good a shot as anybody else at actually winning the general election," Steyn said.
