You make a good point. They don’t even try to compete for the conservative audience.
They compete for the audience their advertisers want to pay the most for: susceptible people.
I call that group ‘dumb sluts’ (that’s hyperbole!).
The advertisers that pay the bill for media naturally want an audience of gullible liberals for their ads, not skeptical conservatives.
Chuck Todd’s job is to attract that audience. It fits him, look at the childishness of his ‘argument.
Polls that attract a susceptible audience are polls that make the network money.
