Vivek Ramaswamy is a stalking horse candidate for the Bush-Ryan-Romney wing of the party. He’s in the race as a backup in case DeSantis failed, which he has.
And of course Ramawamy is being constantly promoted by Fox. Rupert Moloch wants anyone except for Trump because he cannot control Trump.
I heard of this guy when declared his candidacy. He has appeared on every cable news channel and the 3 alphabet channels. Not just Fox news. He was on Newsmax several times.
So you are wrong about just Fox News promoting this guy.
What impressed me about him is he never uses notes to give long speech on any subject. He is head and shoulders smarter than rest of the candidates running.
The first debate will be very interesting to watch.
