From Real Clear Politics, 6/4/2019, featuring Emerson Poll for North Carolina
These 3 new polls from two swing states, Michigan and North Carolina, and a red state, Texas, that some analysts believe may become competitive for the Democrats, continue to show early potential to defeat Donald Trump in November 2020. These are early polls, of course, and they are one particular poll in one particular state, so this information has limitations.
All the major Democratic contenders beat Trump in Michigan, while Biden,Sanders, and Buttigieg beat Trump in North Carolina. Warren and Harris are in a dead heat in North Carolina. In Texas, Biden shows a slim lead over Trump ( 4 points), while the other Democrats are behind Trump but by small amounts.
Overall, positive news for Dems.
