they told me to get to the boston globe. there was an article, mike paulson wrote about a dear friend of mine. in boston, with the sad death of ted kennedy -- sacha: the michael paulson story which would've been on the front page got bumped inside. clergy sexualthe abuse story from a regional thing. kathy shores is a friend from worcester. i made it's one of his columns, and i think it was a resource differential, how the local and howrs were saying worcester, they were not able to complete with the globe in terms of coverage. stories went creaturely -- regionally, to several dioceses. i think, looking at the new site shawat time, what ca kathy daily, these sources were competing against great sources of communications systems. how does that impact -- my question is how does a major story like that -- how does that impact local stories that are just as significant in other areas? ha: that might have been a story where you had a disadvantage if you were smaller because we needed lawyers. i think what made the story so strong

it's coming from the editorial page of the boston globe, which is separate from the newsroom.ealize a lot of people don't necessarily see or care about the difference. and it's already being bashed online as an example of liberal media bias. i think what we're seeing here are editors in the boston globe as one example of a place where editors and producers and anchors want to make a statement, want to get people's attention and pay attention to what trump has been saying in his own words. so that's what the globe says it's doing. using his own words to preview the future. but it is definitely been controversial. it's almost like something out of the onion newspaper that satirical newspaper, but real in life. >> turn it around again. let's see the hard copy. it presents itself differently when you go online. >> there's the whole thing. it does look like a real front page. if you open it up you'll see the actual normal ideas section and you'll see the editorial saying the gop must stop trump. of course massachusetts pretty liberal state. but we know there is a big amount of supp
