How many of those could be done with the amount of control the Dems have had in the past 8 years? They had full control of the government with the barest of majorities for 2 years with 2 senators that were basically liberal Republicans. You got Gaza, but besides that the rest require Congressional action. While in control they did get the biggest investment in green energy ever, they did get substantial increases for infrastructure (including public transport), and they substantially increased the amount of tech that will be made in the US.
Why didn't you get those things done? Because you didn't have the power to do it, just like Dems didn't.
I don't disagree. Different parties have different makeups. Dems are big tent and Repubs are unified single issue voters.
