RENO - Nevada's incumbent representatives in Congress don't face difficult primary election races June 8, but challenges await for the newest member of the delegation, Democratic Rep. Dina Titus.
Titus finds herself on the other side of a political tidal wave that put President Barack Obama in the White House and helped her knock off three-term Republican Rep. Jon Porter in 2008 to become the first Democrat to represent the suburban Las Vegas 3rd District.
Nevada's other two incumbent House members face only token opposition in their primaries and are heavily favored to win re-election.
Two-term Republican Rep. Dean Heller, who represents the rural 2nd District, is challenged in the primary by Patrick Colletti, a Reno pediatrician.
Democratic Rep. Shelley Berkley has no primary opposition in the 1st District.
