It’s harder to marginalize and ignore people with a ton of money.
The media will pull their ignore and demonize routine and money will have nothing to do with that. Remember, the media is not compelled to run an advert from Cruz. What value is money if you can’t put it to good use.
There will come a round of debates where they (CNN, ABC, PBS etc) will invite only top tier candidates, and Cruz, Paul, and whomever else they deem to be second tier will not be invited. And let’s be clear second tier means... conservative.
