* SOPA - don't pass the bill.
* Health care - spend more, if necessary increase the deficit and we'll figure out the problem later through increased taxes or reduced spending elsewhere.
With electoral reform, it's hard to know what the right thing to do is. Everyone wants to stop gerrymandering but what's the alternative? An algorithm based on population and population density? That has its own set of issues. Heck, it's not straightforward even figuring out if a particular district has been gerrymandered or not. And in some cases, such gerrymandering is considered desirable - such as when it creates district where minorities are the majority.
When the problem is hard to define, hard to explain tangibly, hard to provide solutions for, it's no wonder that people don't get motivated to solve it.
Approval voting or ranking are almost universally agreed to be better than what we have (in most places--some places do have that). That alone would make a huge change.
Independent districting commissions would be a big step forward.
Election day holidays would help.
Actually, a lot of the stuff in this proposed bill would help.
You're right that there's open questions out there, but it's not like there aren't solutions that are obvious first steps.
Re: healthcare, I think that's probably even more complicated than electoral reform. For example, missing from your example are cost-cutting measures, like requiring more transparency in pricing and charging, and deregulating certain things to increase competition.
I don't think enough people are exercised about this issue for it to have much chance of going anywhere any time soon.
