I don't think they are, actually.
I don't know the final outcome yet. But I agree history shows the party out of power should do really well in the midterms.
As a middle the road independent myself, I like to see a balance of power. Particularly Dem, and Repubs that are not in the far left/right.
Many Americans are this way, we are the ones that decide elections because we can swing both ways.
I know this is super unpopular here, but the problem with the Republican party is "MAGA"
The "Tea Party" was the precursor to "MAGA", and it's what F'ed McCain, and gave you Obama for 8 years.
I know MAGA is crazy popular with the followers, they are super hard core loyal. However they do not make up enough of the electorate.
