Last night’s primary winners were helped by some last minute inside-the-beltway fundraisers according to a look at Party Time’s database.

Nevada Senator Harry Reid, who will now face Tea Party-backed Republican Sharron Angle, held a star-studded “Pre-Primary Breakfast” at the Liason Hotel in Washington D.C., on May 19th featuring a host of Democratic senators for support, including Sens. Dick Durbin, Max Baucus, Barbara Boxer, John Kerry and Chuck Schumer. Guests and political action committees could attend by paying anywhere from $500-$2,500. According to the invitations sent to Party Time, Reid has held at least seven fundraisers this year.

Fellow Democratic Nevada lawmaker Rep. Dina Titus, of the 3rd Congressional District, who be facing GOP and Tea Party candidate Joe Heck in November, also got a pre-primary boost from labor unions at a fundraiser last week. Titus held a “Friends of Labor Pre-Primary Reception” at the Charlie Palmer Steak house on May 27 for guests paying $1,000-$5,000.

The event was hosted by several labor groups including the Air Line Pilots PAC, the American Postal Workers Union and the International Brotherhood of Boilermakers. Labor interests have been generous to Titus in the past, giving more than $400,000 over the course of her career, representing some of her top donors, according to the Center for Responsive Politics.

Scott Rigell, the newly anointed GOP candidate in Virginia’s 2nd Congressional District, has also gotten into the beltway fundraising game. A Virginia Beach car dealer, Rigell held a “Meet and Greet” fundraiser on March 9th hosted by the National Automobile Dealers Association. Rigell hopes to challenge Democratic incumbent Glenn Nye, who has had his share of fundraisers this year. According to invites sent to Party Time, he’s held at least seven events in 2010, the latest being a May 25th happy hour at Spike Mendelsohn’s Good Stuff eatery hosted by the Young Professionals Happy Hour.

In other June 8th primary news, Arkansas Sen. Blanche Lincoln, defeated her Democratic challenger, Arkansas Lt. Gov. Bill Halter in yesterday’s special election and will face GOP Rep. John Boozman in November. In Virginia’s 5th Congressional District, Democratic Rep. Tom Perriello will face Republican Robert Hurt.

Key toss-up races we’re watching are all Republican primaries to challenge Democratic incumbents in the fall including: The Nevada Senate seat, Nevada’s 3rd Congressional District and Virginia’s 2nd and 5th Congressional Districts. Arkansas will also hold a runoff election for the Democratic senate candidate as incumbent Blanche Lincoln fights a strong challenge from Lt. Gov. Bill Halter.

In Nevada, GOP challengers to incumbent Democrat Senator Harry Reid include businesswoman Sue Lowden, businessman Danny Tarkanian, banker John Chachas, and former Nevada assemblywoman Sharron Angle. In the state’s 3rd Congressional District, freshman incumbent Dina Titus will be challenged by one of eight GOP candidates; frontrunners include Joe Heck, Brad Lord-Leutwyler, and Robert Lelie Lauer.

In Virginia’s 2nd Congressional District, incumbent Glenn Nye will be one of 10 GOP challengers: Ben Loyola, Ed Maulbeck, Bert Mizusawa, Scott Rigell, Jessica Sandlin and Scott Taylor. In the state’s 5th Congressional District, incumbent Tom Perriello will face one of the eight GOP candidates; the frontrunner is state senator Robert Hurt.

With half a dozen golfing fundraisers this weekend from Virginia to Montana, lawmakers must be hoping for good weather.

Reps. Ed Royce (R-CA), Glenn Nye (D-VA), and Tom Rooney (R-FL) will be hosting events involving golf in the Commonwealth of Virginia and they are asking for contributions ranging from $1,000 per individual to $5,000 per team of four. Nye’s event features “special guest” NFL hall of famer Bruce Smith. Senator Baucus (D-MT) is hosting his 10th Annual Fly Fishing & Golf event in his home state this weekend. He’s asking for contributions of $5,000.

Rep. John Larson (D-CT) and House Majority Leader Steny Hoyer (D-MD) will be splitting their time this weekend at the MGM Grand’s spa in Foxwoods and the Lake of Isles Golf Course to benefit Larson’s Synergy PAC. Donors can join them in North Stonington, Connecticut for contributions of $5,000.

Finally, Rep. Steve Israel (D-NY) is offering PACs and individuals the opportunity to attend the US Open with him at Bethpage Black for $5,000 each.

Six golfing events in one weekend may seem like a lot—but if summers past are any indication of things to come, our legislators are just getting started.
