Unfortunately little to no reaction at all, and I don't think there will be more coverage, specially after a plane crashed today carrying a presidential candidate.
I agree. He was in every news TV show, including the biggest of them "Jornal Nacional". Also very good coverage of IMPA, the math institute behind his education.
But sure, now with the sad news about Eduardo Campos he will be nowhere to be seen. I hope in the next months and years he is remembered and popularized (is that a word?).

That's as prime time as you can get on brazilian TV.
He'll get a lot of calls from every channel, newspaper and magazines.
