Today's installment of campaign-related news items from across the country.
* Rep. Jacky Rosen (D-Nev.) made it official today, telling the Nevada Independent that she's giving up her House seat to take on incumbent Sen. Dean Heller (R) next year. Rosen received encouragement from "Nevada's political godfather, Harry Reid."
* Politico reports that congressional Democratic leaders are working on a midterm-election agenda, called a "Better Deal," that is being "polled in battleground House districts," and "aims to convince voters that Democrats have more to offer than the GOP and the self-proclaimed deal-maker in the White House."
* In Oklahoma, Rep. Markwayne Mullin (R) promised voters that, if elected, he'd retire after three terms in order to honor his commitment to the principle of term limits. This week, Mullin announced he'll seek a fourth term next year.
* In Texas, Rep. Beto O'Rourke (D) reportedly raised more than $1 million online in just two months in advance of his campaign against Sen. Ted Cruz (R) next year. That's a decent haul given Cruz's odds of winning a second term.
* Speaking of fundraising, Randy Bryce, the Democratic candidate running to take on House Speaker Paul Ryan (R-Wis.) next year, raised $430,000 in just 12 days last month. That's pretty impressive, too.
* And noting a familiar problem, the Washington Post reports, "There are 10 Senate Democrats running for reelection in states President Trump won, while Republicans, who currently have [52 seats], only have one or two vulnerable candidates. But Republicans have struggled to recruit top candidates in these Trump states."
