Not Even One

There used to be some conservative Democrats. JFK was for a strong defense and was fervently anti-Communist, with an emphasis on using Special Forces for counter-insurgency. He was also a tax cutter. Henry "Scoop" Jackson was strong on national defense and determined to end Soviet tyranny. Sam Nunn was a defense hawk. There is no Democrat in the House or Senate today who carries conservative beliefs like these great Democrats of old held.
