Filing restrictions vary. Like no felons, under active investigation, lives within same jurisdiction.
We definitely have too many candidates. In practice, other filters, rightly or wrongly, cull the herd to only "serious candidates". Basically, ability to raise money and get endorsements. If you squint, they both kinda look like forms of social proof.
The political parties used to be the filter, but now they're impotent. For better or worse.

Maybe not. But name some "journalists" in corporate media who have your credibility and authenticity.
By my definition, you are far more of a journalist than most talking heads and pundits can even claim to be. (Whereas anonymous coward me is not.)
A "professional journalist" also has the resources to do fact checking and corrections (errata).
Most of the news and analysis I consume today comes from podcasts, bloggers, and books.
That's not great.
Using Manufacturing Consent's thesis of media filters, because I don't have another model, it comes down to who is "in charge". Right now, our society's choices for mass news are corporate propaganda and corporate recommenders (algorithmic hate machines). Some people can afford to buy high quality bespoke news. Some are quirky or crazy enough (news junkies) to keep their own ledger (bozo list).
There are some exceptions. HN, metafilter, user groups (aka special interest groups) like some subreddits and ravelry.org, can also provide higher signal to noise over a longer time frame.
