Roll Call has learned that after a number of discussions with the Democratic Congressional Campaign Committee, Clark County prosecutor Robert Daskas plans to file as a House candidate with the Federal Election Commission by summer's end if not sooner - provided he sails through the final vetting stages of the DCCC's recruiting process.

"He's been in talks with the DCCC," said one Democratic source, who declined to be named because of the sensitivity of the recruitment process. "[Daskas] is one they're focusing on at this point."

Daskas' presumptive candidacy would come after months of DCCC failures to field a high-profile challenger to Porter, who Democrats say is increasingly vulnerable in a pure swing suburban Las Vegas district. A Democratic poll from April suggests that just more than one-quarter of local voters want to re-elect Porter and about one-third "want to consider someone else."

The Garin Hart Yang survey of 405 likely voters, conducted March 13-17, had a 4.9-point margin of error.
