“We can’t risk a majority-Dem senate instilling one of their own as Trump’s VP”
Yep. there’s a fairly good chance the Senate might be a 50-50 split.
The GOP is currently a bet $3 to win $1 favorite to take the Senate leaving the chances of it landing 50/50 fairly low.
The Dems have over twice as many seats to defend.
Plenty of them are vulnerable.
