I'd first place a moratorium on all forms of private campaign financing. Then have each candidate allocated the same exact amount of funds to the dime, which naturally come from a public source, and each being allowed the exact same amount of airtime on TV and internet by law.
There would be no lobbies, no private financing, just each office runner with the same financial means and media share to get the message across to voters in a public forum. Then let the best man win as they say.
It is appalling and grotesque the system we have in place, for which the only way to get elected is by raising millions, literally hundreds of millions. What a perversion! Not only is the system not very democratic, but itself makes a farce of democracy, for there is nothing egalitarian about it and nothing sane. Everything's rigged and and the office goes to the highest bidder, among people who only really care about arriving and then maintaining power once they have sold themselves to their financial supporters. And all the money that's thrown into and wasted upon such a system. It's enough to turn one's stomach. All that wealth given to charlatans, when it could be used to contribute to financing a national health care system that's truly public, or spent on rebuilding bridges that risk collapse, repave roads in need of repair, finance the public schools, lower the nation's debt, etc.
And we even treat this quite droll farce at the political national conventions, as a celebration of our so called great democracy. The incipience of our ways defies all logic and reason.
