Muffy is a dog. Muffy cannot bark. Therefore, no dogs can bark.
Textbook logical fallacy.
Of course, politicians can and do buy elections. Today's process practically guarantees this will occur.
>to the extent that any good ideas are removed from the public realm with this scheme, we all lose.
There are other ways to ensure that good ideas come to the fore. And, as the ability to raise funds is not solely based on the quality of one's ideas, there is no feasible way that the democratic process can benefit from unrestrained campaign financing and rulings like Citizens United.
"10 things we think we know, but really don't
1. Money buys the votes of the general public. (Maybe savvy donors just donate to candidates who will win in the hopes of influencing them.)" [edit: quote moved]
Money is necessary but not sufficient in order to become elected.
Politics is not about good ideas. Jim Crow laws existed for decades.
Money alone isn't sufficient to guarantee an election outcome, you still have to execute.
"'American Crossroads, the super PAC founded by Karl Rove, spent $104 million in the general election, but none of its candidates won. The United States Chamber of Commerce spent $24 million backing Republicans in 15 Senate races; only two of them won. Sheldon Adelson, the casino mogul, spent $53 million on nine Republican candidates, eight of whom lost.' It was, as the paper noted, 'A Landslide Loss for Big Money.'"[1]
"When a candidate doubled their spending, holding everything else constant, they only got an extra one percent of the popular vote. It’s the same if you cut your spending in half, you only lose one percent of the popular vote. So we’re talking about really large swings in campaign spending with almost trivial changes in the vote."[2]

But politicians are a simple and superstitious folk, and they do care a lot about fund raising. And in a 50:50 fight, they'll do almost anything for an edge.
Also, while a politician might be in a safe seat, they'll gain a lot of brownie points (e.g. a promotion) if they can funnel some funds to someone in a marginal seat.
That's the sugar coated version. When it comes to people who already have a lot of seniority and don't need the money for their own elections, the ability to transfer funds between their reelection accounts and those of others isn't about "brownie points". It's the raw exercise of political power, and is handled not to praise, but to bury.
