End Foreign Money Influencing US elections

We should make it illegal for any foreign money allowed in our elections. We should also say No more dark influencers like Soros, Koch, Black Rock etc.
In theory I’d like to see all corporate and foreign money removed from politics.
To open up the playing field to the average guy.
We should guarantee thru our broadcast licensing that each candidate of any given race equal psa airtime for free. Limit all donations to $100.00 per candidate per election cycle.
This would open the door for more people to run and not just foks with money and connections.

We should also forbid any former elected official talking high level jobs lobbying the government for 10 years.
As far as lobbying that too needs to be looked at with fresh eyes.
