Trump train keeps rolling
It looks like Donald Trump has become the most caustic and bombastic presidential candidate.
That was a role most thought would go to Gov. Chris Christie.
Aside from Trump's controversy questioning whether Sen. John McCain (R-AZ) was a Vietnam War hero, Trump got into a verbal war with fellow GOP candidate, Sen. Lindsey Graham (R-SC).
Graham started it by referring to Trump as a jackass. Trump responded by calling Graham an idiot, then held up a sign with Graham's personal cell phone number.
Trump continues to lead all GOP polls for president. He is the only candidate above 20 percent.
Previous front-runner Jeb Bush is barely in double digits.
