Tuesday is round two of the current spate of tea party versus establishment matches in Republican primaries.
Voters in Nebraska and West Virginia face choices, with tea party candidates given a decent chance of winning.
Former Maryland Republican Chairman Alex Mooney is the tea party pick in West Virginia's open congressional seat race. he faces two opponents. The winner will vie to succeed Rep. Shelley Moore Capito, who is running for the Senate.
Also closely watched will be the Nebraska Senate race. Midland University president Ben Sasse, former state treasurer Shane Osborn, and bank president Sid Dinsdale are iin what's believed to be a right race.
Sasse has strong support from tea party groups, but Osborn has gotten help from allies of Senate Republican Leader Mitch McConnell of Kentucky. Dinsdale, who has stressed his strong local roots, has gained momentum in recent weeks. The seat is now held by Sen. Mike Johanns, R-Neb., who is retiring.
This week's contests follow the May 6 Republican Senate race in North Carolina, where House Speaker Thom Tillis easily beat a tea party candidate. Next Tuesday, tea party favorites are challenging establishment figures in Idaho, Georgia and Kentucky.
