It's not that Democrats don't raise money, it's that the sources where their money comes from makes them cowards.
If your platform is higher taxes on the rich, and your source of money is the rich, your attacks won't have as much bark.
If your platform is to replace the health care system with single payer, and your source of money is the health care industry, your attacks won't have much bite.
If your platform is to eliminate the role of big money in politics, and your source of money is big donors who like to play in politics, your attacks won't have much determination.
If your platform is to regulate Wall Street, and your source of money is Wall Street, your regulations won't go too far.
That, is the problem with the Democratic party.
Democrats in the last couple decades have implemented policies towards all those platforms. Very curious to say that they dont get what they want.....
