Syndicated columnist George Will told viewers Wednesday on "Special Report with Bret Baier" that Republican presidential frontrunner Donald Trump is "on a glide path" to the nomination after winning the Nevada caucuses and clinching New Hampshire and South Carolina.

"Trump can reasonably feel he's on a glide path to the nomination and therefore he ought to play defense. But the way he plays defense is by offense  by constantly throwing hand grenades and monopolizing the  conversation day by day," Will said.  

The latest attack came from outside the 2016 presidential field by way of 2012 Republican nominee and former Gov. Mitt Romney, R-Mass., who speculated that there could be a "bombshell" in Trump's tax filings.

Will said Romney effectively shifted the conversation to Trump’s finances: "He showed how a gentleman used his stiletto on Neil Cavuto's show by definitely moving to the front burner the issue of tax returns, which will not go away." 

"We haven't seen institutions like the Club for Growth or Americans for Prosperity, which have ample resources, going after the tax returns and other parts of Trump's past and business," Will said.
