Lol... I laugh everytime I see Republicans undo things in a matter of weeks and then 3 years later Democrats are like.. we wish we could do something but it takes time.
It's very easy to break something, but fixing it always takes more time/effort/care. Especially if you want to try to improve it or prevent it from breaking in the same way again. You could give a drunk toddler a hammer and set him lose in a museum and he could be extremely destructive in a very short amount of time, but I don't think I'd be laughing about it or thinking the drunk toddler was especially clever for destroying so much, and I wouldn't fault the staff for taking a long time to restore and salvage what they can.
It takes longer than weeks to plan, but when they enact their plans it doesn't take long. Democrats always play the game of... had we only known they could do that, now our hands our tied. Case in point is when they authorized the COVID-19 pandemic relief and then Trump fired the single person responsible for preventing fraud, and Democrats were like... hmm, we did nazi that coming.
You're cherry picking data to confirm a political bias. I'm not interested in trading counter examples, but if you could provide a scientific source that shows the pattern, that might be actually convincing.
