Delaware Republican congressional candidate Lee Murphy told Breitbart News Saturday that Rep. Lisa Blunt Rochester (D-DE) has achieved nothing in Congress except for obstructing President Donald Trump’s agenda.

Murphy, a former Amtrak locomotive engineer, hopes to unseat Rep. Lisa Blunt Rochester (D-DE) for the state’s at-large congressional district.

Murphy noted that even though the Cook Political Report said that the election gives Rochester a six-point advantage, he can still likely win because the congresswoman has not achieved any victories in Congress.

He told Breitbart News Saturday host Matthew Boyle, “We’re running against a woman who’s done nothing in three and a half years in office except obstruct the president, and of course, she voted for the president … and she aligns herself with the radical Democrat party in Congress.”

Murphy said that he hopes to channel his blue-collar background to win over the union vote in Delaware.

“I’m a blue-collar guy; I worked on a railroad all my life. I was a locomotive engineer for Amtrak,” the Delaware Republican said.

Breitbart News Saturday host Boyle noted that the Republican Party is going through a “big political realignment.” He added that earlier on the show, they had on former Illinois Gov. Rod Blagojevich, who told Boyle why he considers himself a “Trumpocrat.”

Murphy said he sees hope in his election chances considering that the state is “more working-class than ever.”

Murphy said that gun rights are a “hot issue” in the state, saying that “like Virginia, they’re trying to take our rights away in Delaware.”

He added that he sees a “pathway for victory” if there is a “strong Republican turnout” and “dismal turnout” for his Democrat opponent.” Murphy said that Delaware could have a representative who has commonsense values and would actually work with the president to better his state.

Republicans need to retake roughly 18 seats to regain the House majority. If Murphy were to unseat his Democrat opponent, it would make it one district easier for Republicans to retake the majority.

“Delaware will be in the spotlight and need to take this congressional seat back here to help President Trump take back Congress in 2020. I’m confident in our little state,” he said.
