The crux of it to me comes down to the following: I’d prefer Bevins in the Senate over McConnell. However I realistically don’t believe that a go alone Bevins campaign can win against the Dem machine backed Grimes.
So I’d rather not have Bevins as the nominee at the expense of having Grimes in the Senate. Let alone a Dem controlled Senate.
And even under tye scenario where Grimes is going to win, regardless, I also believe that a McConnell-Grimes fight will draw massive amounts of Democrat money to the state (altho notbas much as McConnell-Judd would gave) Thus denying that money to Dems in key GOP races in other states. So even if McConnell is going to lose, it’s better to have him as the nominee so he can suck up as much Dem money as possible, possibly flipping two or three other states to the Republican.
Yes, I’m ignoring McConnells various transgressions in favor of what I consider to be cold hard political mechanics. But as someone else pointed out on a different thread, we’re in the fight of our lives on behalf of Conservatism this year and I don’t see us as having the luxury to play this in other than a cold, hard, political way.
While I disagree, I do understand and appreciate your thoughtful reasoning. Likely you've put far more thought into it than most voters so kudos to you. :-)
