It is hard to imagine ever being able to match that.
BUT ...
1) We have truth on our side.
2) As idealistic as we may sometimes appear, we are truly committed to the wellbeing of the masses, not the few privileged.
3) To the extent that we occasionally, even accidentally mention our core values and the policy ideals, the public strongly aligns with our positions.
The problem is that, as you say, platforming ideas is treated by the Party and most candidates as a quadrennial necessity -- an undesirable task like filing a tax return, that we wish to get over as quickly as possible. But the people feel the pain 265 x 24 every year. The people don't think in election cycles. They think more like paycheck to paycheck, one job to the next job, and major life events (having children, kids entering college, marriage/divorce, major illness, saving for retirement, caring for aging parents, etc.)
We need to a) HAVE good ideas, b) package the most powerful ideas such that we don't weaken our message with lesser splinter issues, and c) sell them EVERY SINGLE DAY.
