Don't believe this but first day of Trumps Campaign Rally.
"Daily Presidential Tracking Poll
The Rasmussen Reports daily Presidential Tracking Poll for Monday shows that 52% of Likely U.S. Voters approve of President Trump’s job performance. Forty-seven percent (47%) disapprove."
Is Rasmussen biased?
"After the 2010 midterm elections, Silver concluded that Rasmussen's polls were the least accurate of the major pollsters in 2010, having an average error of 5.8 points and a pro-Republican bias of 3.9 points according to Silver's model."
