● MD-Sen: Prince George's County Executive Angela Alsobrooks overcame a massive financial deficit to defeat self-funding Rep. David Trone in Tuesday's Democratic primary to succeed retiring Sen. Ben Cardin. Alsobrooks leads 54-42 with the Associated Press estimating that 66% of the vote is tabulated as of Wednesday morning. 

Trone, according to data from AdImpact, outspent Alsobrooks and her allies at EMILYs List $48 million to $7 million on the airwaves, but his advertising onslaught was unable to match the depth of Alsobrook's support from Maryland's political establishment. Overall, Trone self-funded more than $60 million, a record for a primary.
