Today's installment of campaign-related news items from across the country.
* The Pennsylvania Supreme Court yesterday unveiled a new map of congressional districts, and though Republicans still hope to file a lawsuit to block it, NBC News called the new map "the most consequential midterm development of 2018."
* On a related note, while the Pennsylvania GOP intends to attack the map as unfair, Donald Trump weighed in this morning, saying Republicans should challenge the map as a partisan matter.
* Tom Rooney (R-Fla.), a member of the House Intelligence Committee, announced yesterday that after a decade on Capitol Hill, he won't seek re-election this year. By my count, he's the 34th House Republican to announce his or her retirement (12 are retiring from the House to seek higher office, while 22 are leaving elected office altogether.)
* Which gubernatorial races are likely to be the most competitive this year? It looks like the Republican Governors Association has invested $20 million in ad buys in four states: Florida, Arizona, Nevada, and Ohio.
* Among the guests at Conservative Political Action Conference (CPAC) this year will be Donald Trump, Mike Pence, and oddly enough, White House Counsel Don McGahn.
* In Montana, Republican Senate hopeful Troy Downing was charged "with illegally purchasing resident hunting or fishing licenses in Montana while living in California." A local court announced last week that his jury trial will begin in May. Downing has pleaded not guilty.
* And in Colorado, former President George W. Bush tends to keep a relatively low campaign profile, but he'll be in Colorado this week, headlining a fundraiser for Walker Stapleton's Republican gubernatorial campaign. Stapleton, it's worth noting, is Bush's cousin.
