1. Prove it.
2. No I don’t base my electoral strategy on Trump’s tweets. I only made a comment about them. I cannot imagine Sanders capturing the entire electorate including disgruntled Republicans/conservatives (who will vote for Biden btw) to win against Trump.

Recent polls suggest that Biden is leading in battleground states: https://twitter.com/PpollingNumbers/status/1257202275380088832?s=20. Now, these are only polls so they do not indicate a definite result as it is still 6 months out.
