It's December and Trump is polling better than ever nationally

Back in August, I argued that Donald Trump had already peaked, but now it's December and he's polling better than ever nationally.

In my summer column, I observed that, "his support seems to have met resistance at around the 25 percent mark." How wrong I was. Trump has continued to dominate polls, and other than Ben Carson, nobody else has been able to challenge him at the top.

Now that Carson's support has been dropping, Trump is well ahead nationally. With the inclusion of the latest CNN poll showing Trump 20 points ahead of his nearest rival, Sen. Ted Cruz, his national support has reached 30.8 percent, according to an average of polls compiled by RealClearPolitics, topping his previous high in September, before Carson's major surge.

For all the talk of Cruz's surge, he still has less than half of the support that Trump does nationally.
