Reducing vertical space between radio buttons in PyQT

I'm trying to condense the vertical spacing between a group of radio buttons in PyQT and am struggling. I would like the 3 options in the picture to be vertically closer together...

Code for reproducing:

class MyPopUp(QWidget):
def __init__(self, task=None):
    super(MyPopUp, self).__init__()
    self.task = task

    self.setMinimumSize(400,600)

    self.populate_fields()

def populate_fields(self):

    self.task_popup_layout = QVBoxLayout()
    self.setLayout(self.task_popup_layout)

    # When do you need to get it done by
    self.scheduling_header_label = QLabel("<h3>Getting it done</h3>")
    self.task_popup_layout.addWidget(self.scheduling_header_label)

    # Deadline date
    self.deadline_layout = QHBoxLayout()
    self.deadline_date_label = QLabel("When does it need to be complete by?")
    self.deadline_layout.addWidget(self.deadline_date_label)
    self.deadline_dateedit = QDateEdit(calendarPopup=True)
    self.deadline_dateedit.setAlignment(Qt.AlignmentFlag.AlignRight)
    self.deadline_dateedit.setDateTime(datetime.now() + timedelta(days=7))
    self.deadline_layout.addWidget(self.deadline_dateedit)
    self.task_popup_layout.addLayout(self.deadline_layout)

    # Type of deadline
    self.deadline_type_layout = QHBoxLayout()
    self.task_popup_layout.addLayout(self.deadline_type_layout)
    self.deadline_type_label = QLabel("How strict is the deadline")
    self.deadline_type_label.setWordWrap(True)
    self.deadline_type_layout.addWidget(self.deadline_type_label)

    self.deadline_group_layout = QVBoxLayout()
    
    self.deadline_type_layout.addLayout(self.deadline_group_layout)
   
    self.deadline_group = QButtonGroup()
    self.soft_deadline_radio = QRadioButton("Target Deadline")
    self.deadline_group_layout.addWidget(self.soft_deadline_radio)
    self.deadline_group.addButton(self.soft_deadline_radio)
    self.hard_deadline_radio = QRadioButton("Hard Deadline")
    self.hard_deadline_radio.setChecked(True)
    self.deadline_group_layout.addWidget(self.hard_deadline_radio)
    self.deadline_group.addButton(self.hard_deadline_radio)
    self.specific_deadline_radio = QRadioButton("Must be done on this exact day")
    self.deadline_group_layout.addWidget(self.specific_deadline_radio)
    self.deadline_group.addButton(self.specific_deadline_radio)
