As posted here earlier, Maryland's entire congressional delegation is virtually assured of re-election this fall, with the sole exception of Democratic Rep. Frank Kratovil, who is fighting hard to keep his seat.

You can be certain, though, that the state's pols in Washington--all highly competitive, Type A individuals--are closely sifting the primary returns anyway. They're looking for signs: How pleased--or not--are their party's voters are with the job they're doing?

Here's a quick look at those who probably are feeling pretty good today..and a couple who might not be.

Interestingly, the "winners" include the most established and powerful Marylanders in Congress, plus a couple up-and-comers. That's not what you might expect to see in a year variously described as anti-establishment or anti-incumbent.

1. Sen. Barbara A. Mikulski. One of the safest Democratic Senate re-election bets in the country got 82 percent of the statewide primary vote against a half-dozen non-entities (all the figures here are from almost complete election returns). That's down from her 90 percent primary tally last time out; but that was 2004, a presidential primary with a much larger turnout. In her last mid-term primary run, in 1998, she pulled 84 percent.

2. House Democratic Leader Steny Hoyer. The leadership job of the second-ranking member of the House is in serious jeopardy; Hoyer would be demoted automatically if Republicans take control of the House. But he looks stronger than ever with Democrats in his southern Maryland district, an indication that he hasn't neglected his home base while traveling the country to help fellow Democrats. He received 85 percent of the primary vote, up from 83 percent in the last two elections.

3. Rep. Chris Van Hollen. The Montgomery County congressman also has national duties, and mind-bending headaches, as chairman of the House Democrats' campaign arm. But back in his liberal suburban district, he got 93 percent from party voters, up from 88 percent last time and 91 percent in the 2006 midterm.

4. Rep. Elijah E. Cummings. The Baltimore representative was unopposed in the last midterm election and drew 93 percent in 2008. He received 91 percent on Tuesday; that's no worse than an "A-minus" on anyone's report card.

5. Rep. Donna Edwards. The delegation's most liberal member used the last two primaries to dispatch an entrenched Democratic incumbent, Al Wynn, to his new career as a D.C. lobbyist. This time, she scared away Prince George's County State's Attorney Glenn F. Ivey, who ultimately ducked the race, then brushed off a state delegate, Herman Taylor, to win an impressive 83 percent of the primary vote and cement her hold on the seat.
