MSNBC's Joe Scarborough says we need to accept that Donald Trump could be a serious contender in the 2016 presidential election. Trump, the real estate mogul and reality TV host, has said on multiple occasions that he will make an announcement of some kind in the near future. New Hampshire radio station WMUR 9 reported Thursday that the billionaire will make a "major" announcement on June 16 at Trump Tower in New York City and then head to New Hampshire to possibly begin his campaign tour. Many have rolled their eyes at the thought of Trump seriously running, as he has teased a GOP presidential run -- and then not gone through with it -- numerous times before. But Scarborough believes he may be serious this time.
