Dean isn't a stranger to fights both political and the personal. In 2011, Dean made some statements about author Neil Gaiman that he later apologized for being a "name caller." Dean said Gaiman is an author "who I hate," was a "pencil-necked little weasel who stole $45,000 from the state of Minnesota." It is worth noting that, according to Gaiman, the fee was actually $33,600 and was "donated to charity groups."
Dean isn't exactly the most moderate of Minnesota Republicans. He is currently promoting a petition on his website (MattDean.org and not his campaign site which is mattdeanforgovernor.com) to "kill" MNSURE. He vowed in his statement announcing his campaign to "kill and bury MNSURE and go back to doing healthcare the Minnesota way."
Dean's wife, Laura, was a Delegate to the 2016 National GOP Convention in Cleveland. Information is not readily available as to which candidate she was bound to. However, Dean was a District-wide delegate from MN-04. Therefore, we know she was either bound to Rubio (2 of 3 MN-04 Delegates) or Cruz (1 of 3 MN-04 Delegates).
