Paul Sarbanes served MD for 30 years in the US Senate and was well respected. John Sarbanes runs for the US Senate. Jon Cardin, Ben Cardins nephew runs for the US House in MD-3.
Anthony Brown is either going to run for Governor in 2022 or the US Senate in 2024.
A matchup between Anthony Brown-D and Larry Hogan-R will be similar to the 2012 HI US Senate Race between Hirono-D and Lingle-R.
In the 2002 HI Governors Race, Linda Lingle-R narrowly defeated Lt Governor Mazie Hirono-D, Hirono-D the got elected to the US House in 2006. In 2012. Both Hirono-D and Lingle-R ran for the US Senate and Hirono-D won by a landslide margin. I could see a similar situation happening in MD with Brown-D and Hogan-R in 2024. The other Democratic candidates Raskin,Delaney,and Trone are from Western MD. Ruppersberger and Mfume are in their late 70s. The other candidate I have forgot to mention is Frank Kravitol, former US Representative from MD-1 Eastern MD from 2008 to 2010.
