I just read that another joined the Caucus, Kansas Sen. Jerry Moran.

That’s a little surprising as Moran beat Tiahart in the primary who was considered to be more conservative (if only marginally). But that’s great as it means that Moran is serious about getting things under control. Toomey was at the little meet and greet as well even though he hasn’t joined yet.
The more the merrier.
