"i.e. do less bullshitting than the other party (and mean it - really) and they might get somewhere - not holding my breath to"
I'd argue they need to do MORE bullshitting if they want to ever have a majority again. The Republicans win because they're better bullshitters and willing to rig the system. The Dems need to catch on that you don't get extra points for telling the truth, that bending the rules is how the game is played, and obstructionism doesn't cost anything when people go to the ballot box.
