The WSJ's Monica Langley provides insights into Donald Trump's campaign strategies, some of them right out of his book "The Art of the Deal." His target voter is from a think big strategy to get voters across a broad spectrum using the slogan "Make America Great Again," with a knack of tapping into a deep well of voter frustration with the political establishment. How to get attention in the media is the next step Trump tackled by using social media to the fullest - using Twitter often, making statements that attract attention such as the ones on China, Mexico, Senator McCain and Muslims that tap into failure of political correctness to address voter frustration on trade and jobs, immigration and terrorism. The Trump campaign has 14 million followers on Twitter, and 50 million "engagement" accounts on Facebook- that cost very little. Social media is to Trump in 2016 what community networking on the PC dashboard was to Obama in 2008. As the WSJ pointed out in an editorial, the splitting of the Republican vote among many candidates, and the failure of candidates to grasp the nature of the unconventional campaign waged by Trump- descending into attacks based on target groups of voters on every candidate except Trump- created the opportunity Trump has grasped with his knack for improvising along the way. Commonsense campaigning without sophisticated strategies, improvising often along the way, using the available medium of social media at little cost to get the message and slogan across, helped Trump make the deal with voters to upset the political establishment. The Sanders campaign is also based on careful repetition of the same slogan and facts about inequality and lobbyists, over and over again, offering strong action on health care and college tution just as Trump offers strong action on China trade, immigration with the idea of the wall, and barring entry of Muslims for terrorism till "we figure out what's happening." The difference being that Trump thinks big and targets the entire electorate of his party's voters in the primaries from the beginning, and a broad based campaign on many issues. Underestimating your opponent carries many risks in politics, never more so than when you are out of touch or not listening to voter frustration, and fail to speak up to it....
