Looks like Jeff Waldstreicher isn’t going to waltz into the Democratic nomination for the open seat being vacated by Sen. Rich Madaleno, who is running for governor. Dana Beyer let it be known last night that she’s running.

A former eye surgeon and aide to one-term Councilmember Duchy Trachtenberg, Dana has sought election unsuccessfully before in District 18, twice for delegate and last time challenging Rich for Senate. She’s built name recognition, is independently wealthy and willing to spend it on a serious campaign. There is no love lost between Dana and Jeff, so expect this to be tough-fought contest at the very least.

Jeff will expect interest groups to go with him as the established incumbent legislator and work aggressively to persuade them that he will win so they should back him, Dana’s entry provides interesting opportunities for groups that feel Jeff has been insufficiently supportive or doesn’t have their back when push comes to shove and want to send a warning.

Dana has been working hard to organize a slate with candidates for delegate. It will be interesting to see if Jeff does the same and whether and how candidates for delegates choose to plump. I’m sure many will be watching Del. Al Carr, who has built a constituency the district’s municipalities–he was formerly a Kensington Councilman–as well as neighborhood associations and civil activists. There are dangers in joining either camp but also in remaining unaligned.

Fasten your seatbelts District 18, it’s going to be a wild ride!
