AL voters are better off electing Jones to the US Senate and here is why.

If Jones wins tonight, he will be in the US Senate for 3 years. He will lose re-election in 2020 to a non controversial hard right conservative Republican challenger-Mo Brooks or Roger Aderholt.
If Moore wins tonight, he will be in the US Senate for more than 3 years. It is highly unlikely the US Senate will expel Moore or lose in the Republican primary.
