Baltimore (CNN) The cast of Republicans battling for their party's nomination has amounted to divine intervention for Democrats, Vice President Joe Biden said Thursday.

"We may be given a gift from the Lord in the presidential race here," Biden told House Democrats during their annual party retreat in Baltimore. "I don't know who to root for more -- (Sen. Ted) Cruz or...what's that guy's name? He's having a fundraiser for veterans tonight, I'm told."

His name, of course, is Donald Trump, the billionaire businessman who leads most national polls for the Republican nomination. Instead of participating in Thursday evening's Fox News debate in Iowa, Trump says he's holding a fundraiser for wounded servicemen and women.

Biden has never hid his feelings about Trump, calling his immigration message "sick" over the summer and railing against the Republican candidate's plan to bar Muslims from entering the country.
