Of course incumbents are going to be supportive of the system as it was and is, they're incumbents. You can't blame a person in power for maintaining a system giving them power any more than you can blame a bee for pollinating a flower. It's in their nature. The electorate misidentified the solution to their problems. Voters squarely hold the blame in my opinion. You can't vote for an arsonist and then complain when they set fire to everything. Leftists spend their time complaining online and disengaging from the political system instead of voting in primaries against incumbents. Independents and conservatives vote against their own interests consistently while keeping in power a party that is destroying our system of government.
