Well it seems voters wanted to end gridlock in washington, so they voted for those causing the gridlock ... in part because -- once again -- the GOP controlled the message machines, and in part because DEMs ran away from the President and what they accomplished in SPITE of the GOP.
Could they have done more? yes - they could have campaigned on the successes (including controlling ebola) they could done more to highlight GOP obstructionism, from the government shutdown (and how proud they were of it) to the failure to pass job bills, equal pay bills, minimum wage bills, immigration bills, etc etc etc
Could WE have done more? yes - we could have put ballot initiatives on the state ballots to cover a number of issues stalled in congress:
1. minimum wage $10.10/hr, to match the Obama federal contract minimum wage ...
2. equal pay for work of equal value ...
3. student loans at fed rate of interest, interest currently paid or incurred recalculated ...
4. repeal Citizen's United ruling to get money out of politics ...
5. national referendum on tax reform, closing loopholes ...
6. union bill of rights -- that people have a right to join a union ...
7. add Medicare as single-payer option to the ACA ...
8. add a "none of the above" option to all representative categories ...
9. add a voters bill of rights -- that all citizens of the US have a right to vote without obstruction ... that any changes to voter laws, including all "voter ID" laws, would be phased in over a four year period, that photo IDs could be obtained at the polling station the next time a registered person votes, that registration included getting a photo ID for all new registrants, and that the "indelible ink stained thumb" system be used to prevent multiple voting until the transition period is over ...
Do it as a populist movement that crosses party lines and goes around congress to find solutions.
Enjoy
