Trump: "Anybody that hits me, we're gonna hit them ten times harder."

"As an example, if Bush or Rubio or any of them come out, we're gonna just, dollar for dollar, go after them. We have more money than anybody else by a factor of about a thousand... We're gonna start spending a little bit of money over the next three or four weeks."

Remember the kinder, gentler days of "If you get hit, we will punch back twice as hard"?
