Donald Trump is controversial again, thanks to his disparaging comments about Sen. John McCain's war record. 

Trump is surging in the polls and New York Post editorial writer Robert George says that’s because Trump’s brash style is apparently resonating with the Republican base.

“The segment of the party that Trump is appealing to is probably the most conservative. They think anything couched in terms of pathway to citizenship is in their view amnesty,” George told WNYC's Julianne Welby.

But George says Trump’s reputation might change as Republican voters get to know his views about other issues like Iran, ISIS and taxes.
