Totally.  Imagine if someone came running up to you on the street and did what this reporter did.  Waving a mic in your face, demanding an answer, not taking no for an answer, not taking a hint, not being polite.
Just because they are reporters and the fifth estate doesn't give them the right to act like aggressive panhandlers grasping for words, or muggers demanding money.
Public figures are people too.  They have every right to decline speaking to someone on camera.
Like how about act more civil, like, um, booking an appointment through the campaign manager and having a civilized interview?  That strategy was invented years ago and is apparently forgotten.
It might also give more time to write an informed, detailed article than demanding a two second sound bite they can twist into 6 column inches with all the bias they can stuff into it.
