objectives (see 2020 election platform)...the differences have to do with tactics to achieve those ends...and as the BBB Bill creation showed, they are willing to negotiate among themselves...and with others, as well...to craft a solution. During the 2020 primaries there were sharp differences on HOW to provide "Universal Health Care" to Americans...Bernie wanted a 'Single Payer' system, while Biden was more moderate (i.e. improve the ACA)...Biden won handily...and so did ALL the Democrats in 2020, by a 7 Million vote margin...The Dems know how to move the ball forward.
This is decidedly not the case with today's GOP...NO party platform...at all...for 2020...and clearly NO negotiations within the party are allowed...witness their desire to ban Liz Chaney and Adam Kinzinger...and after winning the Electoral College in 2016...NOT the popular vote...the GOP couldn't muster the will to pass even an Infrastructure Bill, much less anything else that would benefit EVERY American.
Why is this so hard for you to understand?
