Democratic Congressional Campaign Committee (DCCC) Chairman Rep. Chris Van Hollen (D-Md.) said on "Fox News Sunday" that other Democrats will not follow Rep. Parker Griffith (R-Ala.) who switched parties this week, citing the Democrats' agenda as his reason. 

"I'm very confident that no other Democrats are going to jump ship," Van Hollen said. 

Reports have surfaced this week that Rep. Chris Carney (D-Pa.) was being courted by GOP lawmakers to make the switch. Carney is a Blue Dog Democrat like Griffith once was, but said that he has no plans to make a switch.

The Maryland Democrat said that he believes that Griffith jumped ship as an act of self-preservation to win reelection but that he
"he miscalculated politically."

Van Hollen said that people will support candidates who stick by their convictions and who do not "blow in the wind."

Looking ahead to the 2010 midterm elections, Van Hollen said "No, I am not going to be happy with losing 20 seats" as some outlets have estimated, but said that Democrats are "not going to be surprised like we were in 1994."
