Senate Democrats are having a very good 2015.
The party has recruited top-tier candidates in each of the four most competitive seats up next November and have another four solid candidates in Republican-held seats that could help them expand the national playing field as they try to retake the Senate after two years in the minority. In most of these states -- though not all -- the preferred Democratic nominee has no serious primary challenge or even the prospect of one looming.
Consider:
* In Nevada, former state attorney general Catherine Cortez-Masto, the preferred candidate of retiring Sen. Harry Reid, is in the race and Rep. Dina Titus isn't.
* In Florida, Rep. Patrick Murphy, a young, aggressive candidate and prolific fundraiser, is running. (The prospect of Rep. Alan Grayson primarying Murphy complicates this recruitment win for Democrats.)
* In Illinois, Rep. Tammy Duckworth, a wounded Iraq war vet, is in. Rep. Bill Foster is out.
*In Wisconsin, former senator Russ Feingold is running.
That quartet of seats are rated as "toss-ups" by the nonpartisan Cook Political Report. And, in each, Democrats have a legitimate "A" recruit. That's pretty darned good.
But the Democratic recruiting successes are even more impressive than that. Dig a layer deeper -- the states Cook rates as "Lean Republican" or "Likely Republican" -- and you see that Democrats have done a very good job of finding serious candidates in them. To name a few: former governor Ted Strickland in Ohio, Rep. Ann Kirkpatrick in Arizona, Secretary of State Jason Kander in Missouri and, just yesterday, former representative Baron Hill in Indiana.
