When a candidate accepts millions of dollars form Rich donors, you bet your bippy he is subservient to the rich donor class. Why do you think the middle class has been getting screwed for 3 decades??
Every time i see that line of reasoning, i wonder what does it mean if the next election cycle Mark Zuckerberg is the only candidate self financing?
Zuckerberg does not have the personality to win any election. He can not resonate with voters. Most Billionaires I observe have the same problem. They could not hold a 30,000 people audience loving them with 2 hour speeches without a teleprompter. Trump is extremely unique candidate.
Keep in mind, Bernie is doing well in spite of not accepting multi-million dollar contributions from the uber rich and Wall Street. So it is not impossible.
