I did a search and of course found the "Senatorial Elections 2010" thread.

I could have put this in GOP now and in future, but I'll try this thread. It can be merged if needed.

Any particular laces catching your eye?

There may be some more conservative Senatorial in the Senate. We'll wait and see.

Senate faces potential influx of conservative Republicans
By Michael O'Brien, NBC News

The Senate is likely to assume an even more conservative tenor come January as a crop of insurgent-minded Republicans replace some of the GOP's old guard in the upper chamber.

A transformation within the Republican Party that was first set in motion during the 2010 midterm elections appears set to continue in the Senate, following in the path blazed in the House during this term of Congress.

“The goal is not only getting the Republican majority, but getting a conservative majority -- a majority of the Republican majority,” said Brendan Steinhauser, the director of state and federal campaigns for FreedomWorks, a group that’s worked to elect Tea Party candidates the last two cycles. “In a lot of ways, we're just getting started.”
Ted Cruz from Texas may be one example:

The Senate’s more than likely to count conservatives like Texas’ Ted Cruz – the former state solicitor general who beat the establishment-backed Lt. Gov. David Dewhurst in the Lone Star State's Senate primary on Tuesday – among its members come next January.
Cruz would replace retiring Republican Sen. Kay Bailey Hutchison, a relative moderate who’s spent 19 years in the Senate.
