Why is McConnell voted back in every time? Maybe his elections results are compromised.

Soros backed money to voters to get them to vote for him.

He's a RINO. He needs to be replaced in Congress, or at least replaced as Speaker.

FWIW

But why wouldn’t they just back a Democrat to replace him?

If he's already in their pocket, they don't need a Democrat to replace him.

Just tell him his share won't come through unless he votes "their way"! They only use him like that on key issues.

He's tainted and has voted against Republicans on more than just a few key issues!

He needs to be replaced.

FWIW

He actively campaigns against conservatives, too

Only the ones he cannot control.

The rest are probably on his payroll!

FWIW

McConnell is known for fixing elections in his flavor. He only wants senators who will support him. How does he have so much power?

Deep state may have control of him. 

They know something about him that they will reveal if he doesn't do something.

But they cannot play that card on him all the time, so they only use him for the things they cannot get done otherwise.

If they didn't want him to have that power, he wouldn't.

That's how corrupt DC works these days.

FWIW

A foreign government has bought him through his wife.

Goes back to the age old... follow the money!

FWIW
