Rush hasn’t made an endorsement yet. He throws his support to candidates after the primary but I don’t recall him coming out for or against a candidate much.
I don’t think Rush is looking to Rand Paul, Lindsey Graham, or Jeb Bush as his pick, if that helps.
You would be correct. Rush does not throw support toward anybody until they win the nomination.
Then, his support is measured .. depending on the relationship he might have had with them in the past.
