North Carolina: Trump 48.6% Biden 46.5%
Arizona: Trump 48.9% Biden 46.4%
IBD/TIPP Presidential Poll. Their poll is showing a 4.0% national lead for Joe Biden. This poll should worry the Trump campaign. These are likely voters. Biden's support is still strong in the cities and suburbs. The Democrat base is also strongly backing Joe Biden. Slightly more than the support that Clinton received from her Democrat base in 2016.
Daily Presidential Tracking Poll (Rasmussen). Today's numbers .... 49% of likely U.S. voters approve of President Trump’s job performance. Fifty percent (50%) disapprove. President Obama was doing 3% better than President Trump at this point in his campaign in 2012. Today's number is below the magical 50% number.
White House Watch (Rasmussen). Today's numbers .... Biden 48%, Trump 47%.
Real Clear Politics. Their averages are showing a Biden victory with a maximum of 319 electoral votes.
