			 In the run up to Wednesday night's third debate for Republican 
			candidates, Trump has averaged a score of 7.3 on Thomson Reuters 
			social media sentiment analysis index in the six weeks since the 
			previous debate. Carson, meanwhile, has averaged negative 3. A 
			reading above 0 signals positive sentiment. 
			 
			For months, despite criticism, gaffes and attacks, Trump held a 
			tight grip on the first-place position in dozens of opinion polls on 
			those seeking the Republican Party's nomination to run in the 
			November 2016 election. 
			 
			But a New York Times/CBS News poll released on Tuesday showed 
			Carson, a retired neurosurgeon, received 26 percent of the support, 
			ahead of Trump for the first time. 
			
			  The real estate developer garnered 22 percent, trailing by less than 
			the 6 percentage-point margin of error. The poll of 575 Republican 
			primary voters was conducted Oct. 21-25. 
			 
			On Twitter, however, Trump generates the most traffic with overall 
			volume of tweets mentioning his name and official Twitter handle 
			(@realDonaldTrump) reaching more than six times Carson's volume 
			(@RealBenCarson). 
			 
			Using a proprietary algorithm, Thomson Reuters social media analysis 
			tool tracks and aggregates positive, neutral and negative tweets 
			with Republican candidates' names and their official Twitter handles 
			in order to generate a sentiment score. The counts are from a 
			representative sample. 
			 
			Since the second debate on Sept. 16, an analysis of daily sentiment 
			scores shows Trump has spent far more time in positive territory 
			than Carson, although Carson's recent improvement in the polls has 
			corresponded with his social media sentiment score trending more 
			frequently in positive territory. His score has edged out Trump's on 
			several days in the last two weeks.

			On Google, Trump was also the most searched candidate ahead of the 
			debate, according to Google Trends on Wednesday. 
			 
			But Carson has a strong presence on Facebook. While his Twitter 
			following (825,000) was significantly less than Trump's (4.7 
			million), his Facebook page was the most popular in the entire 2016 
			race. 
			 
			Carson notched up nearly 7.2 million "engagements" on his 138 
			Facebook posts in October, according to data compiled by social 
			analytics platform, NewsWhip. Engagements consist of likes, shares 
			and comments on posts. 
			 
			By comparison, Trump generated about 4.8 million engagements on his 
			62 Facebook posts.
