Former Vice President Joe Biden has had it with partisan gridlock and political games. He thinks he can still find a way to work with rival Republicans. And he thinks President Donald Trump wakes up each morning determined to further divide America and Americans. In short, the Democratic frontrunner wants to pull his rivals in both parties closer and hug a way to compromise. “Let’s stop fighting and let’s start fixing,” Biden said Saturday in a clear distillation of what his team sees as a winning message, both in his crowded Democratic primary and against Trump in the fall of 2020. That spirit of compromise was the central theme of Biden’s official campaign launch in Philadelphia, the city where he will base his third bid for the Democratic Party’s presidential nomination.
