Some people genuinely believe free markets are the best thing for consumers. I’m all for net neutrality but I don’t think every politician is a sell out for voting against, they were voting according to their beliefs.
That was largely not a Republican nor free-market-supporting move if I recall correctly. While new and more innovative companies would likely take the bankrupt companies' place, there would be a harsh transition period in which blame would be placed on the Democratic leadership at the time.
Plus, regardless of partisanship, it's tough even for those who support free markets to knowingly thrust thousands of constituents into immediate unemployment, both morally and for re-elective purposes.
( If it is truly free, why bail out those deemed too large to fail? )
