Here is my take on it. All of those promises is pissing in the wind, when the Democrats do not have the votes in the Legislature to enact them. Also, I would be remise if I did not also point out that the Democrats have a history of promising things they know they can not enact.
The above being said, what can she really promise to do that has a decent chance of being accomplished?
1. She can promise that if the opportunity arises, she will replace Conservative Justices in all branches of the Judicial with Liberal Judges. (I am a firm believer in the need for there to be Balance between Conservatives and Liberals. Right now, the Judicial Branch is leaning too heavily Conservative in my opinion)
2. She can also promise that she will not support bills that continue to support the Genocide happening in Gaza. (It really is just simply the moral thing to do, since genocide should never be supported).
3. She can also promise that she will use executive actions to strengthen the border and lower the influx of illegals that in turn push a downward pressure on low to no skilled labor wages. (One of the reasons' why you see some low-wage earning men actually supporting Trump or are undecided, is because of this issue. You remove this issue, you increase the possibility that those undecided voters move to support your side).
4. There are more that is within her power as a president to do, but I will leave these 3 as a start.
I am not swayed by promises that I know are nearly impossible to keep. I am swayed by promises I know the candidate has the power to enact. Since I know she has the power to nominate Supreme Court justices, court of appeals judges, and district court judges I am voting for her; understanding that the US Senate normally accepts and confirms those candidates.
